For addition of two unlike fractions, first change them to the like fractions. LCM of 1, 8 = 8 Now, let us change each of the given fraction into an equivalent fraction having 8 as the denominator. = [(4/1) × (8/8)] = (32/8) = [(7/8) × (1/1)] = (7/8) Now, = (32/8) + (7/8) = [(32 + 7)/8] = (39/8) = 4 whole 7/8 Thanks
