Glencoe Math: Course 2, Volume 1 – The Percent Equation

<

Solution

When comparing numbers, it is best to first ensure that they are as similar as possible. Let's consider the given numbers. 88 % ? 0.9 To compare these two numbers, we will first write them in the same form. We can do this by writing the percent as a decimal. Recall that we can write a percent as a decimal by ignoring the percent symbol and moving the decimal point two places to the left.

percent as decimal: 0.88

We got that 88 % is equal to 0.88. Now we compare 0.88 with 0.9 by looking at the tenths. 0. 88 ? 0. 9 Since 8 < 9, 0.88 is smaller than 0.9. 0.88 < 0.9 ⇔ 88 % < 0.9
