ANSWER

As given ;

What number should we subtract from the ratio 19 : 21 so, that it makes 7 : 8.

It means that we have to find out a number which should be subtracted from 19 : 21 to make it in the ratio 7 : 8.

Ratio that make 7 : 8 are :- 14 : 16, 21 : 24, 28 : 32 etc.

The nearest one is “14 : 16”

So, the number which should be subtracted= (19 - 14) and (21 - 16)

Condition is that if both the results are equal then only we can subtract them as told in question.

First result ;

= (19 - 14)

= 5

Second result ;

= (21 - 16)

= 5.

As 5 = 5, they can be subtracted.

{So, your answer is :- 5.}

So, your answer is :- 5.
