Adding fractions is a way to find the total amount when you have two or more parts. To add fractions, you need to make sure that the denominators (bottom numbers) are the same. If they are not the same, you can find a common denominator by multiplying the numerators and denominators by the same number. Adding fractions is an important part of mathematics, and it is used in many different ways to find totals and solve problems

### Convert Fractions to Repeating Decimals

To convert a fraction to a repeating decimal in math, you can divide the numerator (the top number) by the denominator (the bottom number). You will end up with a repeating decimal, which represents a certain fraction.

### Dividing Fractions

Dividing fractions is just like dividing any other numbers, but with a few special rules to remember. You are finding how many times one fraction will fit into the other, so the answer will often be a larger number or fraction than either of the original fractions.

### Error Estimation, Approximation, and Rounding

When you round a number, there is always a small difference, or error, between the rounded number and the actual number. Error estimating is a way to find out how much the rounded or approximate number is different from the actual number.

### Multiplying Fractions

Multiplying fractions is just like multiplying any other numbers, but with a few special rules to remember. You are finding the product of the parts, so the answer will often be a smaller fraction than either of the original fractions.

### Percentages

A percentage is a way to show a number as a part of 100. Imagine you have 100 pieces of candy, and you want to divide it among your friends. To figure out how many pieces of candy each friend gets, you can use percentages. Percentages are used in many different ways, like to show discounts, to calculate grades in school, or to compare the size of different things. They are a useful way to describe and compare parts of a whole.

### Rounding and Approximations

Rounding means making a number simpler by "rounding" it to the nearest whole number or to a specific place value. Approximations are used when you want to estimate a number that is close to the actual answer, but not exact.

### Rule of Three or Cross-multiplication

What is the rule of three or cross-multiplication in Math? In Mathematics, given an equation between two fractions or rational expressions, representing ratios or proportions, it is a way to solve the value for the variable. It is used in percentages, interets and so on. Learn how to calculate it step by step.
