Question

Work out the following questions ​

Answer 1

Answer:

as follow

Step-by-step explanation:

a

$\frac{2}{7} \div \frac{3}{4} = \frac{2}{7} \times \frac{4}{3} = \frac{8}{21}$

b

$\frac{5}{9} \div \frac{5}{1} = \frac{5}{9} \times \frac{1}{5} = \frac{1}{9}$

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!
