How do you subtract dissimilar fraction? - Answers

You make the denominators the same, by multiplying the fractions by the denominator of the other fraction. Then you can subtract them. For example, 4/5 - 7/8. Make the denominators the same by multiplying "4/5" by 8/8*, which gives 32/40. Multiply "7/8" by 5/5*, which gives 35/40. Denominators are now the same, so subtract: 32/40 - 35/40 = -3/40. * 8/8 and 5/5 are each equal to 1, so you aren't changing the value of the fraction. Sometimes it makes the calculation easier to find the lowest common denominator (LCD) first: 7/24 - 5/36 = ? The LCD is 72 ... it's the smallest number that both 24 and 36 go into evenly. 24x3 = 72, and 36x2 = 72, so: 7/24 x 3/3 - 5/36 x2/2 = 21/72 - 10/72 = 11/72.
