Solve using equivalent ratios.

The width of the new card is 9 inches.

<u>SOLUTION: </u>

Given, we have to solve using equivalent ratios. Wayne has a recipe on a 3-inch-by-5-inch index card that he wants to enlarge to 15 inches long.

We have to find width of the enlargement

Now, dimensions of card is $\bold{\frac{(3 \text { inch })}{(5 \text { inch })}}$

Let the new width of card be n inches .

So, New dimensions of card is $\bold{\frac{(n \text { inch })}{(15 \text { inch })}}$

Then, equivalent ratio is $\bold{\frac{3}{5}=\frac{n}{15}}$

$\bold{\frac{3}{5}=\frac{n}{15} \rightarrow n=\frac{3}{5} \times 15 \rightarrow n=3 \times 3 \rightarrow n=9}$
