Question

People with severe hearing loss were given a sentence and word recognition test six months after they got implants in their ears. The patients scored an average of 82% on the test. Write this percent as a decimal.

Answer 1

The way to write a percent as a decimal is to drop the percent sign. The put a decimal point at the end of the number and move it 2 places to the left. Add a zero in front of the decimal so that it's correct. To change it back to a percent, move the decimal point 2 spaces to the right. Add the percent sign back. 0.82
