A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given

The length of the patio is 4.5 centimeters.

The actual length of the patio.

Let the actual length of the patio be x.

And the length of the patio is 4.5 centimeters.
