# +-x and dividing fractions

### by Brandon

## Multiplying

Example:

1/2

2/2

Step 1. You multiply the top numbers:

Like,

1/2=1 × 2/2

2/2

Step 2. You multiply the bottom numbers:

1/2=1 × 2/2

252 × 510

Step 3. You Simplify if you need to

2/1

105

## An example would be

## Dividing fractions

## Adding fractions (both ways)

- Step 1: You need to make sure the bottom numbers (the denominators) are the same
- Step 2: You add the top numbers (the numerators), put the answer overthe denominator
- Step 3: You simplify the fraction if needed

## Here, this will explain it

## Subtracting is easy

Subtracting is just like adding

The LCM of 11 and 22 is 22... So the LCD is 22. You just need to change the numbers

Done!

## Dividing is easy

Keep change flip

Example:

1/1

1/6

Step 1. You turn the second fraction upside down (it becomes a reciprocal):

1 becomes 6

6/1

Step 2. You multiply the first fraction by that reciprocal:

(multiply tops ...)

1/6=1 × 6/6

212 × 12

(... multiply bottoms)

Step 3. You simplify the fraction:
