Concept: Algebraic Manipulation

D

Step-by-step explanation:

Amy spent 1/6 of the 90 dollars on school supplies, which means to multiply 1/6 by 90

1/6*90

6 and 90 are both factors of 3, so cancel

1/2*30

30/2

$15

Answer is D

PS. you can put the fraction 15/90 and see that it is equal to 1/6 if you're not sure/ if you want to double check :)

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
