Answer:

12 is 90% of what number? 13.33

12% of 72 is what number? 8.64
The first one is 13 rounded up. You do the is/of. 12 = is and the of is unknown. next you do 90% over 100. You have now 12/? and 90/100. You multiply the 12 by 100 and get 1,200 then divide by 90 and I got 13.3 or round it up to 13.
