3 3/8 * 3 1/5 + 3 1/5 * 1 5/12 - 4 1/6 * 3 1/5 = 3 1/5*(3 3/8 + 1 5/12 - 4 1/6) = 3 1/5*(3 + 1 - 4 + 3/8 + 5/12 - 1/6) = 3 1/5*(9/24 + 10/24 - 4/24) = 16/5 * 15/24 = 2 * 3 / 3 = 2
3 3/8 * 3 1/5 + 3 1/5 * 1 5/12 - 4 1/6 * 3 1/5 = 3 1/5*(3 3/8 + 1 5/12 - 4 1/6) = 3 1/5*(3 + 1 - 4 + 3/8 + 5/12 - 1/6) = 3 1/5*(9/24 + 10/24 - 4/24) = 16/5 * 15/24 = 2 * 3 / 3 = 2
