Answer 2

Answer:

The given 1st number is 80% of the second number.

To find:

What percentage is first number of the second number

Solution:

Given : 1st number = 20% of 3rd number

    2nd number = 25% of 3rd number

Let us assume that the third number is 100. Then,

1st number = 20 and 2nd number = 25

Dividing 20 by 25, we get

$\frac { 20 } { 25 } = \frac { 4 } { 5 } = 0.80$

Then its percentage will be,

$\frac { 0.80 } { 100 } = 80 \%$

Hence, 1st number is 80% of the second number.
