Priya mixes : 2 1/2 cups of water with 1/3 cup of orange juice concentrate.

Diego mixes 1 2/3 cups of water with 1/4 cup orange juice concentrate.

So, to get the same taste with 100 cups for each recipe,

let the number of cubs of orange = x

for Priya mixes:


\begin{gathered} 2(1)/(2)\colon(1)/(3)=100\colon x \\ \\ (5)/(2)\colon(1)/(3)=100\colon x \\ \end{gathered}

Solve for x:


\begin{gathered} ((5)/(2))/((1)/(3))=(100)/(x) \\ (5\cdot3)/(2\cdot1)=(100)/(x) \\ \\ x=(2\cdot100)/(5\cdot3)=(200)/(15)=13(1)/(3) \end{gathered}

So, Priya will need 13 1/3 cubs of orange

And for Diego mix:


1(2)/(3)\colon(1)/(4)=100\colon x
\begin{gathered} (5)/(3)\colon(1)/(4)=100\colon x \\ \end{gathered}

solve for x:


\begin{gathered} ((5)/(3))/((1)/(4))=(100)/(x) \\ \\ (5\cdot4)/(1\cdot3)=(100)/(x) \\ \\ x=(1\cdot3\cdot100)/(5\cdot4)=(300)/(20)=15 \end{gathered}

So, Diego will need 15 cubs of orange
