Question

The dimensions of a dollar bill are 6.125 inches by 3.375 inches. However, a dollar bill created 1891 to 1928 had dimensions of 7.3125 inches by 3.125 inches. Are the two dollar bills similar?
A. No because the sides are not congruent.
B. No because the sides are not proportional
C. Yes because the angles are congruent
D. Yes because the sides are proportional

Answer 1

D. Yes because the sides are proportional

Answer 2

For the sides to be proportional, the following must be true:

\[\frac{6.125}{7.3125} = \frac{3.375}{3.125}\]I hope that you can see they cannot be equal without reaching for any sort of calculator...
