I won't explain... I will solve in detail. You'll get it!

1. 72 is what percent of 90?
72 is 72/90=(72/8)/(90/9)=9/10=0.90=90% of 90

2. find 10% of 240?
10%=10/100=0.10
10% of 240=(0.10)(240)=24
3. 90 is what percent of 360?
90 is 90/360=(90/10)/(360/10)=9/36=(9/9)/(36/9)=1/4=0.25=25% of 360
4. find 8% of 120?
8%=8/100=0.08
8% of 120=(0.08)(120)=9.6
