The "foot-to-height" ratio in fraction style is: Allie: 21133 Mom: 24152 So the ratio for Allie is 21 : 133 By dividing both values by 7 we get 21/7 : 133/7 = 3 : 19 And the ratio for Mom is 24 : 152 By dividing both values by 8 we get 24/8 : 152/8 = 3 : 19 The simplified "foot-to-height" ratios are now:
