Exercises Numbers, fractions and percents

Example 5.63 from Prealgebra, 5.6 Ratios and Rate

Ratios and Rate: example 5.63

Bob drove his car $525$ miles in $9$ hours. Write this rate as a fraction.

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution

$525 miles in 9 hours$

Write as a fraction, with 525 miles in the numerator and 9 hours in the denominator. $\frac{525 miles}{9 hours}$

$\frac{175 miles}{3 hours}$

So $525$ miles in $9$ hours is equivalent to $\frac{175 miles}{3 hours} .$

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Write the rate as a fraction: $492$ miles in $8$ hours.

How did it go?
