A lowest common multiple is used to compare two or more numbers. A single number cannot have a lowest common multiple.
First a common denominator must be found. The denominators are 2,3,4,8. 24 is the Lowest Common Denominator. Now convert all the fractions with 24 as the denominator. ⅓=8/24 ⅛=3/24 ½=12/24 ⅜=9/24 ⅞=21/24 ⅔=16/24 ¼=6/24 ⅝=15/24 ¾=18/24 ½ =12/24 The denominator will be 24. Add the numerators. 8+3+12+9+21+16+6+15+18+12 =120 The fraction is 120/24 which is equal to 5.
The common denominator of 4/8 and 11/15 is 90.
the answer is 8 because 8x12=96 and there is no more common denominator of 8 and 96 above 8 so the answer is 8
