7%
.07 (Move the decimal point two places to the left!)
Convert to a percent:
.873
87.3% (After moving two spaces, we still have a decimal at the end of our percent.)
Convert to a fraction (Remember to SIMPLIFY):
.89

How do I convert a percent to a decimal?

478% (Now that's a big percentage!)
Convert to a fraction (Remember to SIMPLIFY):
25%

I divide!

3.31
3 (31/100) If we have a number in front of our decimal, then that number becomes a whole and we get a mixed fraction.)
How do I convert a fraction into a percentage?
I divide it out and then move the decimal point two spaces to the right!
Convert to a percentage:
2(1/10)
