Find a common denominator: 3 x 4 x 17 = 204
Write each of the fractions with this denominator:
1/3 = (1 x 4 x 17) / (3 x 4 x17) = 68/204 Multiply both the numerator and denominator by 4 x 17.
1/4 = (1 x 3 x 17) / (3 x 4 x 17) = 51/204 Multiply both the numerator and denominator by 3 x 17.
3/17 = (3 x 3 x 4) / (3 x 4 x 17) = 36/204 Multiply both the numerator and denominator by 3 x 4.
1/3 + 1/4 + 3/17 = 68/204 + 51/204 + 36/204 = (68 + 51 + 36)/204 = 155/204
