How do i enlarge a shape using a ratio

Determine your ratio. For example, assume your ratio is 9 out of 10.

Multiply the numerator and the denominator by the same number. For example, 9 times 10 equals 90 and 10 times 10 equals 100, so the new ratio is 90 out of 100.

Divide the numerator and denominator of the ratio by the same number to reduce the ratio. In the example, 90 divided by 50 equals 1.8 and 100 divided by 50 equals 2, so your ratio is 1.8 out of 2.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
