The decimal form of 4.5 is .045 when 4.5 is a percentage. Understanding place values help identify the decimal form of a percentage.
Know MoreOne way to rewrite a percent in decimal form is to determine the number as a fraction of 100. The easiest way to do that is to create a division problem in which the percentage is the numerator and 100 is the denominator. Since 4.5 already has a decimal in it, the fraction can be multiplied by 10 over 10 to make it a rounded number. Thus, the equation becomes 45 divided by 1,000. It is important to note that 10 divided by 10 is one and does not ultimately change the value of the equation. The resulting answer is .045. Another easy way to create the decimal form of a number is to move the decimal point to the left by the number of necessary places.
