Question

Work out the following questions ​

Answer 1

as follow

Explanation:

a

`(2)/(7) / (3)/(4) = (2)/(7) * (4)/(3) = (8)/(21)`

b

`(5)/(9) / (5)/(1) = (5)/(9) * (1)/(5) = (1)/(9)`

Answer 2

Step 1. Turn the second fraction (the one you want to divide by) upside down

(this is now a reciprocal).

Step 2. Multiply the first fraction by that reciprocal

Step 3. Simplify the fraction (if needed)

Example:

1/2 ÷ 1/6

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

1/6 becomes 6/1

Step 2. Multiply the first fraction by that reciprocal:

(multiply tops ...)

1/2 × 6/1 = 1 × 6/2 × 1 = 6/2

(... multiply bottoms)

Step 3. Simplify the fraction:

6/2 = 3

This is how you divide fractions. Now try it your self!
