3 3/5 : 3 3/5 + 6/7 * 2 1/3 * 1 1/4 = 3,5

1) 3 3/5 : 3 3/5 = 18/5 * 5/18 = 1

2) 6/7 * 2 1/3 = 6/7 * 7/3 = 2

3) 2 * 1 1/4 = 2/1 * 5/4 = 5/2

4) 1 + 5/2 = 2/2 + 5/2 = 7/2 = 3,5

5/7 * 1 13/35 + 2/3 - 1 2/5 * 5/14 = 1 43/294

1) 5/7 * 1 13/35 = 5/7 * 48/35 = 48/49

2) 1 2/5 * 5/14 = 7/5 * 5/14 = 1/2

3) 48/49 + 2/3 = (144 + 98) / 147 = 242/147

4) 242/147 - 1/2 = (484 - 147) / 294 = 337/294 = 1 43/294
