Question

A recipe for flour and coca at a ratio of 3:1 cups A. Fill to the table to show different proportions amountsB. Explain why these amounts are proportional

Answer 1

Given that a recipe calls for flour and cocoa at a ratio of 3: 1 cups

The table below shows the different proportional amounts.

SOLUTION

If the amount of cocoa is 1, let the amount of flour would be x, hence,

$\begin{gathered} 3\colon1=x\colon1 \\ x=3 \end{gathered}$

If the amount of flour is 2, let the amount of cocoa be y

$\begin{gathered} 3\colon1=2\colon y \\ \frac{3}{1}=\frac{2}{y} \\ y=\frac{2}{3} \end{gathered}$
