You can eliminate the decimal point by multiplying by 100. You can keep the same value you started with by dividing that result by 100. 4.01 = (4.01*100)/100 = 401/100

Any decimal is easily converted to a fraction this way. Remove the decimal point and express the resulting value over 1 followed by the number of zeros formerly to the right of the decimal point.

__Example__with 1 decimal place: 0.1 = 01/10__Example__with 3 decimal places: 84.323 = 84323/1000 Then, you can reduce the fraction by dividing out the factors of 2 or 5 that may exist. 1.25 = 125/100 = 25/20 both numerator and denominator divided by 5 = 5/4 both numerator and denominator divided by 5 again.
