Question: 5 of 36: . alice bought 8\9 of a pound of grapes and ate 1\3 of a pound. how many pounds were left? . a. 8\6. b. 7\3. c. 7\9. d. 5\9.

In order to solve this question, you just need to equalize the denominator

in 8/9 , 8 is the numerator and 9 is the denominator
in 1/3, 1 is the numerator and 3 is the denominator

in order to change 1/3 into denominator 9, you just need to multiply both numerator and denominator with 3 , which give us :

1/3 = 3/9

now back to the question

Alice has 8/9 , and ate 3/9 of them, this will give us :

8/9 - 3/9 = 5/9 which is left

so the answer is option D

hope this helps

8/9 - 1/3 = 8/9 - 3/9 = 5/9
