Amaya has an inflatable pool that she filled 3/4 full for her cousin on a hot summer day. After playing all day, the pool was 3/10 full. How much of the water was lost? Simplify your answer.
If Amaya filled the pool 3/4 full and after playing all day it was 3/10 full, then 3/4 full - 3/10 full = <<3/4-3/10=15/40>>15/40 of the water was lost. Answer: \boxed{\dfrac{15}{40}}.
can you repeat again
I apologize for the confusion. Let me clarify the steps:
Amaya filled the pool 3/4 full, which can also be written as 30/40 full (since both 3/4 and 30/40 represent three-fourths of a whole).
After playing all day, the pool was 3/10 full, which can also be written as 12/40 full (since both 3/10 and 12/40 represent three-tenths of a whole).
To find the amount of water lost, we need to subtract the final amount from the initial amount:
30/40 - 12/40 = 18/40
So, 18/40 of the water was lost. This fraction cannot be simplified any further. Therefore, the answer is \boxed{\frac{18}{40}}.
