Question

The ratio of Isabella's money to Shane's money is 3:11. If Isabella had 33$,how much money do Shane and Isabella have together? Use diagrams to illustrate your answer

Answer 1

ratios stay the same, they are either multiplied or divided by some factor to make it larger or smaller.

shane : Isabella
3:11
( times 3)
9:33

Answer 2

3/11 = 33/x
cross multiply
(3)(x) = (33)(11)
3x = 363
x = 363/3
x = 121 .....so Shane has 121

together, Isabella and Shane have : 33 + 121 = 154 <==
