Chapter 1, Problem 86

Write each decimal as a fraction. (Do not write in lowest terms.) 0.82

Verified step by step guidance
1
Identify the place value of the decimal. Since 0.82 has two digits after the decimal point, it is in the hundredths place.
Write the decimal as a fraction with the decimal digits as the numerator and 100 as the denominator: \(\frac{82}{100}\).
Note that the problem asks not to simplify the fraction, so leave it as \(\frac{82}{100}\) without reducing.
Express the fraction clearly as the final answer in fraction form: \(\frac{82}{100}\).
Review the process: converting a decimal to a fraction involves using the place value of the last digit to determine the denominator and writing the digits as the numerator.
