A ratio is an ordered pair of numbers a and b where b does not equal 0.

A proportion is an equation in which two ratios are set equal to each other.

Given

Carter has 60 balloons.

4/12 of the balloons are black, and

3/12 of the balloons are white.

How many red balloons does Carter have?

The black balloon will be

The white balloon will be

Then the sum of all red, white, and black balloons is 60. Because Carter has 60 balloons.

Thus the number of red balloons is 15.

109 is the nearest whole number/final answer! : )

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
