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

1. 72 is what percent of 90?
72 is 72%2F90=%2872%2F8%29%2F%2890%2F9%29=9%2F10=0.90=90% of 90

2. find 10% of 240?
10%=10%2F100=0.10
10% of 240=%280.10%29%28240%29=24
3. 90 is what percent of 360?
90 is 90%2F360=%2890%2F10%29%2F%28360%2F10%29=9%2F36=%289%2F9%29%2F%2836%2F9%29=1%2F4=0.25=25% of 360
4. find 8% of 120?
8%=8%2F100=0.08
