Leilani practiced piano for 3/5 of an hour. Sarah practiced piano for 7/8 of an hour.

ivolga24 [154]

Answer:

The number of hours did Sarah practice more than Leilani is $\dfrac{11}{40}$ hours .

Step-by-step explanation:

Given as :

The time for which Leilani practiced piano = $\dfrac{3}{5}$ hours

The time for which Sarah practiced piano = $\dfrac{7}{8}$ hours

Let the number of hours did Sarah practice more than Leilani = T hours

<u>Now, According to question</u>

The number of hours did Sarah practice more than Leilani = $\dfrac{7}{8}$ hours - $\dfrac{3}{5}$ hours

Or, T = $\dfrac{35-24}{40}$ hours

Or, T = $\dfrac{11}{40}$ hours

So,The number of hours did Sarah practice more than Leilani = T = $\dfrac{11}{40}$ hours

Hence, The number of hours did Sarah practice more than Leilani is $\dfrac{11}{40}$ hours . Answer
