how u would solve this question with showing ur work So you just find 20% of the number (divide 20 by 6) then times it by 5 to get 100% So 20/6 is 3.33... (this is 20% of the number) and 3.33... x 5 = 16.67 (this is the answer) For 30% more than 30, you follow the same basic rules So 30 is 130% of the number So first you find 10%, which is 130% divided by 13..........
