# Fractions

### By: Abe Hoyos

1. If you have a denominator that is different then the other denominator find the closest common factor of both of them.

2. If you have 2 denominators the same then leave them alone, they'll be the denominator for your answer

3. After you do one of those steps, add the numerators together. Then that numerator will be the numerator for the answer. Also then you have the numerator and denominator for your answer.

FYI: If your numerator is bigger than your denominator make it a mixed number.

## Subtracting Fractions

1. If you have a denominator that is different then the other denominator find the closest common factor of both of them.

2. If you have 2 denominators the same then leave them alone, they'll be the denominator for your answer

3. After you do one of those steps, subtract both numerators. Then that numerator will be the numerator for the answer. Also then you have the numerator and denominator for your answer.

## Multypling Fractions

1. Simplify the fractions if not in lowest terms.
2. Multiply the numerators of the fractions to get the new numerator.
3. Multiply the denominators of the fractions to get the new denominator.

Simplify the resulting fraction if possible or simplify across.

## Dividing Fractions

1. Turn the second fraction (the one you want to divide by) upside down
(this is now a reciprocal).

2. Multiply the first fraction by that reciprocal
3. Simplify the fraction (if needed)

Simplify the resulting fraction if possible or simplify across

1. Line up the decimal points.

2. Add as usual from left to right, column by column.

3. When you’re done, place the decimal point in the answer in line with the other decimal points in the problem.

## How To Subtract Decimals

## How To Multiply Decimals

1. Perform the multiplication as you would for whole numbers.

2. When you’re done, count the number of digits to the right of the decimal point in each factor and add the result.
