Exercises Numbers, fractions and percents

Example 5.58 from Prealgebra, 5.6 Ratios and Rate

Ratios and Rate: example 5.58

Write each ratio as a fraction: ⓐ $45 to 18$ ⓑ $45 to 18 .$

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

ⓐ

$15 to 27$

Write as a fraction with the first number in the numerator and the second in the denominator. $\frac{15}{27}$

Simplify the fraction. $\frac{5}{9}$

ⓑ

$45 to 18$

Write as a fraction with the first number in the numerator and the second in the denominator. $\frac{45}{18}$

Simplify. $\frac{5}{2}$

We leave the ratio in ⓑ as an improper fraction.

Your turn

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

Write each ratio as a fraction: ⓐ $21 to 56$ ⓑ $48 to 32 .$
