Two complementary angles, A and B, have measures in the ratio of 7 to 23, respectively. What is the ratio of the measure of the complement of angle A to the measure of the complement of angle B? Express your answer as a common fraction.
7/(7+23) x 90 =21 degrees, angle A
23/(7+23) x 90 =69 degrees, angle B
B/A =69/21 =23/7
