Question

Find the missing number of each unit rate 21/7=?/1 72/12=?/1

Answer 1

21/7 = 3/1 72/12 = 6/1

Answer 2

In these questions, we have equivalent ratios given and we have to find the missing number .

For the first one, we have

`(21)/(7)= (x)/(1)`

Here the missing number is represented by x .

Dividing both 21 and 7 by 7,

`(3)/(1) = (x)/(1)`

That gives, x=3

For the second question, we have

`(72)/(12) = (x)/(1)`

Dividing both 72 and 12 by 12, we will get

`(6)/(1) = (x)/(1)`

That gives x=6
