2. 21/5 x 24/7 = 147/120 = 1 27/120 = 1 9/40
3. 128/100 x 37/10 = 1280/3700 = 128/370 = 64/185
4. 21/2 x 3/5 = 105/6 = 17 3/6 = 17 1/2
5. 7/3 + 5/3 : 7/3 = 7/3 + 5/3 x 3/7 = 7/3 + 35/9 = 21/9 + 35/9 = 56/9 = 6 2/9
6. 26/7 : (11/4 - 5/3) = 26/7 : (33/12 - 20/12) = 26/7 x 12/13 = 338/84 = 4 2/84 = 4 1/42
