Answer 1

Answer:

For finding what % of 80 is 20

we've to use the formula

$\frac{20}{80} \times 100 \\ \frac{20}{8} \times 10 \\ \frac{200}{8} \\ = 25$

therefore the answer is 25% ,as 25% of 80=20

here

options are in decimal

we know

% is a number by 100

that is ,here it's 25%

thus

25/100=0.25

therefore option c) 0.25 is the correct answer.

Let's check whether it's correct or not by using

$\frac{25}{100} \times 80 = 20 \\ \frac{1}{4} \times 80 = 20 \\ \frac{80}{4} = \frac{40}{2} = 20 \\ 20 = 20$
