Answer:

Step-by-step explanation:

The perimeter is adding all 4 sides

We know one side is 9

The other three sides are in the ratio

1:2:4

Multiply by x to give the side lengths

x, 2x, 4x

The Perimeter is

9+ x+2x+4x=65

9+7x=65

Subtract 9 from each side

9-9 +7x =65-9

7x = 56

7x/7 = 56/7

x=8

The shortest side is 8

we just need add x next to ratio and sum them all to get perimeter

9 + x + 2x + 4x = 65

7x = 56

x = 8

well since 8(x)<9<16(2x)<(32(4x), then

the shortest side is 8

Match the fractions with Equivalent percentages

Mrrafil [7]

In order to match each of the pairs you need to divide the numerator by the denominator to make it into a decimal.

Below are the pairs:

21/25 = 84%

13/20 = 65%

2/5 = 40%

3/4 = 75%

3/5 = 60%
