Alex mixes 2/3 pounds of walnuts with 3/5 pound of dried fruit. To create more of the same mixture, how many pounds of walnuts d
igomit [66]
ANSWER

Alex needs to mix one pound of dried fruit with
1 \frac{1}{9}
pounds of walnuts.

EXPLANATION

It was given that, Alex mixes
\frac{2}{3}
pounds of walnuts with

\frac{3}{5}
pounds of dried fruit.


We can write the ratio,

\frac{2}{3} :  \frac{3}{5}

Let
x
represent how many pounds of walnuts Alex needs to mix with one pound of dried fruit.


Then we can again write the ratio,

x: 1
We can therefore write the proportion,


\frac{2}{3} :  \frac{3}{5}  = x: 1

This can be rewritten as,

\frac{ \frac{2}{3} }{ \frac{3}{5} }  =  \frac{x}{1}

We solve for x to obtain,

\frac{2}{3}  \times  \frac{5}{3}  = x


This implies that,

x =  \frac{10}{9}

x = 1 \frac{1}{9}

Hence Alex needs to mix
1\frac{1}{9}
pounds of walnuts with one pound of dried fruit.
