Answer:

a) 18/6 = b/4 = r/5

b) b = 12, r = 15

Explanation:

a) The proportion will simply state the fact that the ratio of shirt dimension to logo dimension is the same for all. We'll use 'b' for the bottom dimension and 'r' for the upper right dimension. Then the proportions are ...

shirt/logo = 18/6 = b/4 = r/5

__

b) In each case, multiply by the denominator to find the value of the variable.

3(4) = b = 12

3(5) = r = 15

The bottom dimension is 12 cm; the top right dimension is 15 cm.
