The number of teaspoons of key lime zest to make 30 cupcakes is
35/8 or 4 3/8
Given,
Margaret uses 1 3/4 teaspoon of key lime zest to make 12 cupcakes.
She wants to make 30 cupcakes.
We need to find how much key lime zest will Margaret use.
Example:
1 bag = N mango
Then to find the number of mangoes in 5 bags we need to multiply 5 on both sides.
5 bags = 5 x N mangoes.
We have,
1 3/4 teaspoons of key lime zest = 12 cupcakes
7/4 teaspoons of key lime zest = 12 cupcakes
7/4 = 12 cupcakes
Multiply 30 on both sides.
7/4 x 30 = 30 x 12 cupcakes
Divide both sides by 12.
7/4 x 30/12 = 30 cupcakes
35 / 8 = 30 cupcakes
or
4 3/8 = 30 cupcakes
This means,
35/8 or 4 3/8 teaspoons of key lime zest to make 30 cupcakes.
Thus the number of teaspoons of key lime zest to make 30 cupcakes is
35/8 or 4 3/8.
