Write down some possibilities of the 2 numbers that add up to 32 first.
16+16, 15+17, 14+18, 13+19, 12+20
12 and 20 works because 12*5=60 and 20*3=60
Your answer is 12 and 20 (:
1510*0.02=$30.20 which is larger than $20.00. 2%= 0.02
Assuming the rule is multiply by 6, I would say 216.
For this problem you can multiply by the reciprocal giving you (1/16)*(4/3) which gives you 4/48, then 1/12.
