A cake recipe says to use 3 cups of flour for every 2 cakes. Write a proportional equation to calculate the amount of flour needed, $$ f $$, for any number of cakes, $$ c $$.

Question

UpStudy AI · Accepted Answer

The proportional equation is $$ f = \frac{3}{2}c $$. To create a proportional equation for the amount of flour needed for any number of cakes, we start with the given ratio of flour to cakes. The recipe states that 3 cups of flour are needed for 2 cakes. We can express this relationship as a fraction: $$ \frac{3 \text{ cups of flour}}{2 \text{ cakes}} $$ To find the amount of flour $$ f $$ needed for $$ c $$ cakes, we can set up the following proportional equation: $$ \frac{f}{c} = \frac{3}{2} $$ To solve for $$ f $$, we can cross-multiply: $$ f = \frac{3}{2}c $$ Thus, the proportional equation to calculate the amount of flour needed for any number of cakes $$ c $$ is: $$ f = \frac{3}{2}c $$

A cake recipe says to use 3 cups of flour for every 2 cakes. Write a proportional equation to calculate the amount of flour needed, \( f \), for any number of cakes, \( c \).
