Thus 37 1/2% means 37 1/2 hundredths. Place 37 1/2 over 100, and you have a fraction. Multiply numerator and denominator by 2 and you have the fraction 75/200 Divide the numerator and denominator by 25, and you end up with 3/8.

Convert from percent to common fraction. 66 2/3% Can someone please help, I have a friend that knows the answer but she can't explain how she got the answer because she just knows what the answer is without having to do any math.

Most of us do—not because we're any smarter than you, but because of our mathematical experience.

I've shown you how to calculate 37 1/2%. Just follow the same technique to calculate
66 2/3%
