How to multiply the Fraction
To multiply fraction u just need to multiply the top number with top number
and then multiply the bottom number with bottom number and then simplify fraction
if it possible

## Example 1

 1 × 2 2 5

Step 1. Multiply the top numbers:

 1 × 2 = 1 × 2 = 2 2 5

Step 2. Multiply the bottom numbers:

 1 × 2 = 1 × 2 = 2 2 5 2 × 5 10

Step 3. Simplify the fraction:
 2 = 1 10 5

## Example 2

 1 × 9 3 16

Step 1. Multiply the top numbers:

 1 × 9 = 1 × 9 = 9 3 16

Step 2. Multiply the bottom numbers:

 1 × 9 = 1 × 9 = 9 3 16 3 × 16 48

Step 3. Simplify the fraction:
 9 = 3 48 16

How to divide fraction
First u need to switch second up side down then just multiply them as normal

## Example 1

 1 ÷ 1 2 6

Step 1. Turn the second fraction upside-down (it becomes a reciprocal):

 1 becomes 6 6 1

Step 2. Multiply the first fraction by that reciprocal:

 1 × 6 = 1 × 6 = 6 2 1 2 × 1 2

Step 3. Simplify the fraction:

 6 = 3 2

## Example 2

 1 ÷ 1 8 4

Step 1. Turn the second fraction upside-down (the reciprocal):

 1 becomes 4 4 1

Step 2. Multiply the first fraction by that reciprocal:

 1 × 4 = 1 × 4 = 4 8 1 8 × 1 8

Step 3. Simplify the fraction:

 4 = 1 8 2
