Answer 1

Answer:

5

Step-by-step explanation:

this is what I do, I see how many times 20 can go into 100, that is 5 times. and sense the mystery numbers 20% is 1, you can just leave it at 5. To double check your answer, count 1 5 times. 1 goes into 5 5 times, and 20 goes into 100 5 times.

Answer 2

You said "20% of (number) = 1".

-- 20% means 0.2

-- in math, "of" usually means "times", so ...

0.2 · number = 1

Divide each side by 0.2:

number = 1 / 0.2

number = 5
