To add the given fraction (dissimilar fraction-have different denominators) get the Least Common Denominator 31/5 + 72/3 + 51/15 To find LCD (one way is to know the multiples of the number) 5 = {5,10,15,20} 3= {3,6,9,12,15,18} 15 = {15,30,45} since we have a least common multiple that is 15 that will be the LCD of the given denominators = 93/15 + 360/15 + 51/15 (add the fraction) = 180/15 =12 (answer expressed in simplest form)
