The answer to this question would be: 45/128 hours= 0.351 hours

In this question, Leyla played sports for 3+3/4 hours and Puno plays it 3/8 as long as Leyla time. Then, to know how much Puno playing duration you need to multiply the ratio with Leyla playing time. The calculation would be:

Puno playing time= 3/8 Leyla playing time
Puno playing time= 3/8 (3 +3/4 hrs)= 3/8 * 15/16= 45/128 hours
