Question

2 1/2 of milk makes 5 servings.How many cup of milk are needed to make 8 servings?

Answer 1

notice 2 1/2 is 5/2, from 5/2 to 5 you multiply by 2, from x to 8 you also multiply by 2, so x = 8/2 = 4

Answer 2

\[2.5\rightarrow5\]
\[x \rightarrow 8\]
\[5x \rightarrow 2.5*8\]
x\[x \rightarrow 5*2.5*8 = 4 \]
so 4 cup milk needed
