How do you find the answer of fractions with different denomators? - Answers

Well first of all you find the least common multiple of the denominatorsex:3/5+ 2/9List 5's multiples5: 10 15 20 25 30 35 40 45 50 55 60 65 70Then list 9's multiples9: 18 27 36 45 54 63 72 81 90Then what is the lowest number in the list that they have in common?45!So rename the denominators so that they say /45Then what?You find out what you multiply the first denominator by to get the new denominators5 X 9 = 459 X 5 = 45 (because that's just how it is)So then you have to multiply the numerator by the same number as you multiplied the denominatorSo it would be3 X 9 = 27 So the first fraction would be 27/45and then it would be2 X 5 = 10 So the second fraction would be 10/45THEN ADD!27/45 + 10/45 = 37/45
