When converting decimals to fractions, we must first find their Greatest Common Factor (GCF), such as 10. This allows us to multiply the numerator and denominator by ten until we obtain integer numbers before simplifying them further – in this instance, 1.5 would become 3/2 as its fraction equivalent.

## What is a fraction?

Fractions are mathematical symbols used to represent parts of wholes. A fraction comprises a numerator and denominator separated by an imaginary line known as the fraction bar, with one number placed above and one below.

Fractions come in various forms, yet all follow similar principles. They can be divided into proper, improper, and mixed fractions for easy classification.

Proper fractions are any fractions in which the numerator value is smaller than the denominator value, such as 3/5, 5/7, and 11/13. Conversely, improper fractions include 2/9, 13/10, and 17/3, which contain numerators larger than denominators values.

To convert decimals to fractions, first, locate the lowest common denominator. Next, divide the numerator and denominator by this number to determine their respective parts; then, attempt to simplify your fraction as much as possible.

Use this method to convert any number into a fraction. For instance, to convert 1.5 into a fraction, divide by 15 and multiply by 10 to get its numerator and denominator, respectively. Once this information is in hand, simplify it by finding common divisors.

Once your fraction has been simplified to its simplest form, it can be applied to any mathematical problem. Furthermore, using this technique, you can convert decimals to percentages; for instance, if you need to know what percentage something represents, divide by 100, then multiply the result by 10. This will give you a decimal that represents it!

Fractions are an essential element of mathematics; understanding them is vital for success. By mastering their fundamentals early, students can progress further with their studies and explore more complex topics; this will ultimately result in better grades on exams and make life simpler.

## What is a mixed number?

Mixed numbers are fractions composed of whole and proper bits; for instance, 3 1/2 is considered eclectic because it combines both elements; 3 is an integer, while 1/2 represents an appropriate fraction. Mixed numbers can describe any fraction between two whole numbers more quickly than improper fractions, as their numerator contains real numbers while their denominator contains proper bits.

When dividing a mixed number, you must first convert it to an improper fraction. To accomplish this, multiply both numerator and denominator by their common factor, which will reduce to its lowest terms; e.g., if 15 and 10 have 15 as their common factor, then to bring 1.5 down to its lowest terms, you must divide by 15 which produces an answer of 3/2.

Once your fraction is simplified, you can begin your calculations. This means adding whole numbers and fractions together – for instance, 3 + 1 = 4. When subtraction is involved, split mixed numbers into entire numbers and proper fractions before subtracting one from another (e.g., 5 – 2/3 = 3). Finally, once this step has been completed, add any remainder to the original fraction, e.g. 3 + 1 = 5.

Sometimes it may be necessary to convert a mixed number into an improper fraction and vice versa. To do this, first, rewrite it as an improper fraction before multiplying its numerator and denominator by its reciprocal number to find its quotient. Once that quotient has been obtained, you can rewrite your mixed number as an exact fraction.

Whether you are adding, subtracting, multiplying, or dividing, understanding how to work with mixed numbers is an invaluable skill that will allow you to solve more complex fraction-based problems faster and save you time by not having to convert mixed numbers to improper fractions before performing calculations.

## What is a decimal number?

Decimal numbers are any numerical expression written with a decimal point and denominator with an integer power of 10. Each digit in a decimal represents one-tenth of a unit, such as 0.0.1 or 0.25. They can represent whole numbers or fractions and are usually written with the numerator on top and the denominator at the bottom.

Decimal numbers have many real-life applications; when paying for fruit or ice cream, we often say the price is $2 and 50 cents (2.50), which uses decimals. They’re also commonly used by computers as an efficient way of representing large numbers of bits, allowing them to complete calculations more quickly.

When we divide decimal numbers, we start from the denominator and move up toward the numerator to establish how many equal parts there are. After this, we divide the numerator and denominator to obtain our fraction. If our decimal has multiple factors, we cancel them out to reduce the effort required.

Decimal numbers are frequently used to represent fractions in multiplication and division since they are much easier to manipulate than numbers that consist of whole and decimals. When adding or multiplying decimals, we will use the commutative property of multiplication to ensure accurate results – this rule should help avoid mistakes that lead to inaccurate answers.

There are also specific decimal numbers that cannot be reduced to fractions even after we simplify them to their lowest terms due to having an infinite number of digits after the decimal point. These types of decimals are known as terminating decimals, and they’re typically used to represent sequences of values.

## What is a percentage?

A percentage is an expression that indicates the proportionality between something else and itself. It can be written as fractions, decimals, or ratios and is usually represented with the symbol “%.” For example, 50% can be written as half (0.5) or one-twelfth (1/12).

A percentage can be used to compare two numbers or describe the amount of something in a larger group, making it useful in science, business, and everyday life. It can help determine how many of a population have certain diseases by calculating its percentage; you could also use ratios to represent anything left over from dividing larger groups by themselves.

When calculating percentages, it is crucial to remember that one percent is equal to one-hundredth part of the whole. This makes fractions with 100 as their denominator easier than those with fractions with thirds or twelfths as denominators.

To calculate a percentage, find and divide its numerator by its denominator, then multiply this result by 100 to obtain its percentage value.

Percentages can also be calculated by using the unitary method to divide one number by another whole number and then multiplying that result by 100; for instance, to find out what percent of total beads are red, you could divide red beads by authentic beads and multiply that result by 100% to get your percentage of red dots that make up that total number of beads.

Percentages can be helpful when determining how many percent of an overall number a specific number makes up. Add it to the total and divide it by 100 for an accurate result.

Percentages can also help when you want to compare two numbers and identify which one is greater. For instance, if one amount of money exceeds another amount by more than 10%, using percentage calculations you can quickly determine which amount is more significant by adding up each percentage and multiplying that sum by the total number of numbers compared.
