able to prove how much you have learned so far with FRACTION FEST 2021!
All you need to do is go through each question and add the fractions with like denominators
-- AND DON'T FORGET TO SIMPLFY! They won't accept the answer unless it's simplified!

um what is the question answer choices???

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
