Will mark brainliest for an explanation and the RIGHT answer! Im testing you guys!

10 out of 50 hours were spent playing football. [tex]\frac{10}{50}[/tex][tex]=\frac{1}{5}[/tex]. Divide 1 by 5 to find the percentage.
[tex]\frac{1}{5}=0.2=20[/tex]%
20% of the total hours were spent playing football.
I hope this helps :)
