Ben went to a flower shop and saw that 12 roses cost $18.96. To determine how much 5 roses would cost, Ben wrote the proportion below. Explain
why this proportion is incorrect. Then, write and solve a correct
proportion. *
12
18.96
5

12 roses/18.86

12/18.96=5

this proportion is incorrect since the other side just says 5 and it needs to be in fraction form and have a variable as the numerator/denominator.

12/18.96=5/x

cross multiply

12x=18.96*5

12x=94.8

/12 both sides

x=7.9

$7.90

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
