45 is a "whole number." 45 can be represented as 45 over 1, or 45/1. However, any whole number can be also represented as a quantity of fractional parts, such as halves, thirds, or tenths. The easy way to to this is to multiply top and bottom (numerator and denominator) of the number as a fraction (placed over 1) by the same number, the number representing the fractional part. Examples:
Represent 45 as a number of thirds: 45 = 45/1 = (45*3)/(1*3) = 135/3.
Represent 45 as a number of tenths: 45 = 45/1 = (45*10)/(1*10) = 450/10.
0.45 = 45/100 = 9/20 0.45 = 45%
Make it over 100 (45/100) then reduce to 9/20
45% = 45/100 = 9/50
