Question

ava is running in a race from city square to city park, which is 30 blocks away. she has run 15 blocks so far. ava wants to know what percent of the distance she has run so far. a percent is a rate per 100. find an equivalent ratio where the total number of blocks is 100. blocks run (part) 15 total blocks (whole) 30 100

Explanation:

Step1: Set up equivalent ratio

Let $x$ = blocks run for 100 total.
$\frac{15}{30} = \frac{x}{100}$

Step2: Solve for $x$

Cross-multiply: $30x = 15 \times 100$
$30x = 1500$
$x = \frac{1500}{30} = 50$

Answer:

50
