Answer:
The number of hours did Sarah practice more than Leilani is [tex]\dfrac{11}{40}[/tex] hours .
Step-by-step explanation:
Given as :
The time for which Leilani practiced piano = [tex]\dfrac{3}{5}[/tex] hours
The time for which Sarah practiced piano = [tex]\dfrac{7}{8}[/tex] hours
Let the number of hours did Sarah practice more than Leilani = T hours
Now, According to question
The number of hours did Sarah practice more than Leilani = [tex]\dfrac{7}{8}[/tex] hours - [tex]\dfrac{3}{5}[/tex] hours
Or, T = [tex]\dfrac{35-24}{40}[/tex] hours
Or, T = [tex]\dfrac{11}{40}[/tex] hours
So,The number of hours did Sarah practice more than Leilani = T = [tex]\dfrac{11}{40}[/tex] hours
Hence, The number of hours did Sarah practice more than Leilani is [tex]\dfrac{11}{40}[/tex] hours . Answer
