If 80% of a number is 20, what is 20% of the number?

The answer is 5. 80% is 4/5, so to figure out the number, divide 20 by 4 and multiply by 5 to get 25. Then divide that by 5 because 20% is 1/5. I hope this helped!

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
