(6 2/5 : 1 8/25 - 7 1/5 * 7/24)/(3 3/5 - 2 2/3) = 2 291/308
По действиям:
1. 6 2/5 : 1 8/25 = 32/5 : 33/25 = 32/5 * 25/33 = 160/33 = 4 28/33
2. 7 1/5 * 7/24 = 36/5 * 7/24 = 21/10 = 2 1/10
3. 4 28/33 - 2 1/10 = 4 280/330 - 2 33/330 = 2 247/330
4. 3 3/5 - 2 2/3 = 3 9/15 - 2 10/15 = 2 24/15 - 2 10/15 = 14/15
5. 2 247/330 : 14/15 = 907/330 * 15/14 = 907/308 = 2 291/308
