Answer:


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

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*(3)/(5)= \frac {x}{1}*1\\


(3)/(5)=x


0.6=x

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