4 2/9 * 2 4/7 + 1 2/9 * 2 4/7 =

2 4/7 * (4 2/9 + 1 2/9) = 2 4/7 * 5 4/9 =

18/7 * 49/9 = 2/1 * 7/1 = 14/1 = 14

2 5/6 * 6 2/3 + 3/10 * 6 2/3 - 6 2/3 * 1 1/3 =

6 2/3 * (2 5/6 + 3/10 - 1 1/3) =

6 2/3 * (2 25/30 + 9/30 - 1 10/30) =

6 2/3 * (2 34/30 - 1 10/30) =

6 2/3 * 1 24/30 = 20/3 * 54/30 =

2/1 * 18/3 = 36/3 = 12
