Which one of these proportions is true?
A) 3/5 = 7/11
B) 9/6 = 15/10 (Correct Answer)
C) 3/4 = 9/16
D) 2/5 = 5/10
Explanation:
To determine if proportions are equivalent, cross multiply the numerator and
denominator across the equal sign. Here, 9 * 10 = 90, and 6 * 15 = 90. Therefore,
the proportions are equivalent. No other set of proportions allow the products
of cross multiplication to be equal.
