CPM Homework Help : CC1MN Problem 6-37

Richard’s strategy for changing a percent to a decimal is to put the decimal point in front of the percent number. An example of his work is shown at right. Do you agree with Richard’s method? Explain your reasoning.

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

Hint:

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

Possible Answer:

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