Exercises Numbers, fractions and percents

Example 6.6 from Prealgebra, 6.1 Understand Percent

Understand Percent: example 6.6

Convert each percent to a decimal:

ⓐ $135%$
ⓑ $12.5%$

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

ⓐ

$135%$

Write as a ratio with denominator 100. $\frac{135}{100}$

Change the fraction to a decimal by dividing the numerator by the denominator. $1.35$

ⓑ

$12.5%$

Write as a ratio with denominator 100. $\frac{12.5}{100}$

Change the fraction to a decimal by dividing the numerator by the denominator. $0.125$

Your turn

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