Question

At the Souvenir Shop, gemstone souvenirs cost $11.60 for 5. Which proportion can be used to find the cost of just 1 gemstone?

A. 11.60/x = 1/5
B. x/11.60 = 1/3
C. 11.60/1 = x/5
D. x/11.60 = 1/5

these are fractions by the way

Answer 1

D. If 11.60 of them 5, then in your proportions they would need to be on the same side (both numerators or both denominators) and D is the only answer where this is true.
