Answer:
[tex]\boxed {\boxed {\sf \frac {3}{5} \ or \ 0.6 \ cups \ of \ flour}}[/tex]
Step-by-step explanation:
Let's set up a proportion using this setup.
[tex]\frac { flour}{ eggs}=\frac { flour}{ eggs}[/tex]
We know that 3 cups of flour are needed for every 5 eggs.
[tex]\frac {3 \ cups \ flour}{5 \ eggs}=\frac { flour}{ eggs}[/tex]
We don't know how many cups are needed for 1 egg, so we say x cups for 1 egg.
[tex]\frac {3 \ cups \ flour}{5 \ eggs}=\frac { x \ cups \ flour}{ 1 \ egg}[/tex]
[tex]\frac {3 }{5 }=\frac { x }{ 1 }[/tex]
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.
[tex]1*\frac{3}{5}= \frac {x}{1}*1\\[/tex]
[tex]\frac{3}{5}=x[/tex]
[tex]0.6=x[/tex]
For every 1 egg, 3/5 or 0.6 cups of flour are needed.
