To get rid of the decimal point in the numerator, you count the numbers after the decimal in 22.55, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers, and so on. Therefore, in this case you multiply the numerator and denominator by 100 to get the following fraction: 2255/100. Then you need to divide the numerator and denominator by the greatest common divisor (GCD) to simplify the fraction. The GCD of 2255 and 100 is 5. When you divide the numerator and denominator by 5, we get the following: 451/20.
