A recipe calls for 3 cups of flour for every 5 eggs. How many cups of flour do you need for every 1 egg?

kodGreya [7K]

Answer:

$\boxed {\boxed {\sf \frac {3}{5} \ or \ 0.6 \ cups \ of \ flour}}$

Step-by-step explanation:

Let's set up a proportion using this setup.

$\frac { flour}{ eggs}=\frac { flour}{ eggs}$

We know that 3 cups of flour are needed for every 5 eggs.

$\frac {3 \ cups \ flour}{5 \ eggs}=\frac { flour}{ eggs}$

We don't know how many cups are needed for 1 egg, so we say x cups for 1 egg.

$\frac {3 \ cups \ flour}{5 \ eggs}=\frac { x \ cups \ flour}{ 1 \ egg}$

$\frac {3 }{5 }=\frac { x }{ 1 }$

We are solving for x, so we must isolate the variable. x is being divided by 1. The inverse of division is multiplication, so multiply both sides by 1.

$1*\frac{3}{5}= \frac {x}{1}*1\\$

$\frac{3}{5}=x$

$0.6=x$

For every 1 egg, 3/5 or 0.6 cups of flour are needed.
