Question

Jack is making a cake using his mom's recipe. the recipe requires 1 1/2 cups of milk. he plans to make 2 1/2 cakes. How much total milk will he need for his cakes?

Answer 1

Step-by-step explanation:

Given that for one cake the amount of milk used is

`1cake=1(1)/(2)cups`

Let number of cup sof milk to be used of 2 1/2 cakes be represented as

`x`

By applying the comination below, we will have th expression as

`\begin{gathered} 1cake=1(1)/(2)cups \\ 2(1)/(2)cakes=x \end{gathered}`

Cross multiply, we will have

`\begin{gathered} 1* x=1(1)/(2)*2(1)/(2) \\ x=(3)/(2)*(5)/(2) \\ x=(15)/(4) \\ x=3(3)/(4)cups \end{gathered}`

Hence,

The total milk he will need for 2 1/2 cakes will be

`3(3)/(4)\text{ }cups\text{ }of\text{ }milk`
