7-89.

Richard's strategy to change a percent to a decimal is to put the decimal point in front of the percent number. Below is an example of his work. Do you agree with Richard's method? Explain your reasoning. Homework Help ✎

8% = 0.8
80% = 0.80
800% = 0.800

Should 8%, 80%, and 800% all be represented as equivalent decimals?
If not, there is a flaw with Richard's strategy.

No, because converting from a percent to a decimal involves dividing by 100 or shifting the decimal place to the left twice.
