Chapter 1, Problem 153

Write each percent as a decimal. 7%

Verified step by step guidance
1
Recall that to convert a percent to a decimal, you divide the percent value by 100.
Write the percent as a fraction over 100: \(7\% = \frac{7}{100}\).
Divide 7 by 100 to convert the fraction to a decimal: \(\frac{7}{100} = 0.07\).
Therefore, the decimal equivalent of 7% is 0.07.
Remember that moving the decimal point two places to the left is another way to convert a percent to a decimal.
