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.
Continue ReadingOne 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.

Full Answer >To read a decimal, say the number to the left of the decimal point as a whole number. Use the word "and" to indicate the decimal point. Read the number to the right of the decimal point as a whole number, ending with the place value of the last digit.
Full Answer >When rounding decimals, the number value of the last retained decimal is increased by 1 if the number in the next decimal place is 5 or greater. If the next decimal is less than 5, the number value of the last retained decimal simply remains the same.
Full Answer >A fraction can be converted to its equivalent decimal by dividing its numerator by its denominator. For example, the fraction 3/4 can be converted to a decimal by dividing its numerator (3) by its denominator (4), which results in 0.75, its equivalent decimal. The fraction 5/8 can be similarly converted to a decimal by dividing 5 by 8, which results in 0.625.
