Question

Eva is short on frosting! She works in a bakery and has 12 cakes to frost, but she is short 418 cups on the amount of frosting required. She decides that she will spread the frosting she has among the 12 cakes. She makes a sign for the cakes and names them by the value that represents the amount of frosting on each cake compared to the amount it should have. What does the sign say?

Answer 1

Answer:

-11/32

Step-by-step explanation:

Answer 2

The frosting which will be short on each of Eva's 12 cakes shared equally on each will be $\frac {11}{32}$

Number of cakes to frost = 12

Shortage on required frosting = $4 \frac{1}{8}$

Spreading the frost on each of the 12 cakes available :

Divide the shortage on required frost by the number of cakes

Shortage on required frosting ÷ Number of cakes to frost

$\frac{33}{8} \div 12 = \frac{33}{8} \times \frac{1}{12} = \frac{(33\times1)}{96} = \frac {11}{32}$

Therefore, each frosted cake will be short of $\frac{11}{32} \: cups$
