� Fraction: shows part of a whole as a numerator/denominator. � Numerator: the part of the fraction that you have or have used � Denominator: how many the whole is broken into � Decimal: the decimal is read as “and” so if you have been reading a number as one hundred and thirty you have actually been saying 100. 30 not 130! � Percent: Remember that percent is out of 1 whole. 100% means you have 1 whole, 80% means you have 80 out of 100 that makes a whole.
� Changing a fraction to a decimal is as easy as dividing the numerator by the denominator. � Example: 4/5 means 4 divided by 5. Since there are no 5’s in 4 you must put a decimal behind the 4 and add a zero. Thus 4/5 is. 80
� Since percent is how much of the whole you have with 100% being 1 whole if you multiply the decimal by 100 it converts the decimal to a percent. � Example: � (Yes . 80 x 100 = 80% guys you move the decimal 2 places right!) Remember each 0 moves the decimal 1 place right!
� If you can go F – D – P then you can go P –D – F! � Percent to Decimal: ( HUMMM you multiplied to get to percent so let’s divide to go back the other way!) Divide the percent by 100 or yes……. . move the decimal 2 places left!
� Ha Ha you thought you were done with place value…. Nope it’s BACK! � To convert from decimal to percent you must first determine the place value of the last digit in the decimal. That determines the denominator! � The decimal becomes the numerator without the decimal! � THEN REDUCE!
