How to solve this question. I need to show my work for this question.

IrinaK [193]

Step-by-step explanation:

Recall that 1 dozen = 12 so 4 dozen cookies has a total of 48 cookies. We are going to use the following ratios to solve the problem:

$\left(\dfrac{3\:\text{eggs}}{48\:\text{cookies}}\right)$ and $\left(\dfrac{48\:\text{cookies}}{3\:\text{eggs}}\right)$

a) $12\:\text{eggs}×\left(\dfrac{48\:\text{cookies}}{3\:\text{eggs}}\right) = 192\:\text{cookies}$

b) 18 dozen cookies = 216 cookies

$216\:\text{cookies}×\left(\dfrac{3\:\text{eggs}}{48\:\text{cookies}}\right) = 13.5\:\text{eggs}$
