Question

alicia buys a 5 pound bag of rocks for a fish tank. She uses 1 1/8 pounds for a small fish bowl. How much is left?

Answer 1

amount left =
`3(7)/(8)` pounds

Step-by-step explanation:

the original bag is 5 pounds

We know that she used
`1(1)/(8)` of a pound

Therefore, the remaining amount can simply be computed by subtracting what she used from the original weight

Therefore:

amount left = 5 -
`1 (1)/(8)`

amount left =
`3(7)/(8)` pounds

Hope this helps :)

Answer 2

To find the answer to this question, we just need to subtract the amount Alicia used from the total amount.

5 pounds - 1 1/8 = 3 7/8 pounds.

After Alicia used some of the rocks for her fish tank, she has 3 7/8 pounds of rocks left.
