Answer:

Explanation:


13) (5)/(x)=(20)/(16)

In the numerator, 20 ÷ 4 = 5

So, x = 16 ÷ 4 = 4

5 : 4 = 20:16

14)


(2)/(9)=(12)/(x)

In the numerator, 2*6 = 12

So, x = 9*6 = 54

2:9 = 12 : 54

15)
(x)/(1)=(30)/(3)

In the denominator 3 ÷ 3 = 1

So, 30 ÷ 3 = 10

10 : 1 = 30 : 3


16)(x)/(5)=(21)/(35)

In the denominator, 35 ÷ 7 = 5

x = 21 ÷ 7 = 3

3 : 5 = 21 : 35


17) (21)/(x)=(7)/(2)

In the numerator, 7 *3 = 21

So, x = 2*3 = 6

21: 6 = 7 : 2
