Пошаговое объяснение:
3) ответ: 6 1/2
1) 2 - 1 7/12 = 5/12
2) 3/8 - 1/6 = 9/24 - 4/24 = 5/24
3) 5/12 : 5/24 = 5/12 * 24/5 = 2
4) 2 * 3 1/4 = 2 * 13/4 = 13/2 = 6 1/2
=============
4) ответ: 1/20
1) 7/10 - 2/5 = 7/10 - 4/10 = 3/10
2) 1/4 + 5/6 = 3/12 + 10/12 = 13/12
3) 3/10 * 13/12 = 13/40
4) 13/40 : 6 1/2 = 13/40 : 13/2 = 13/40 * 2/13 = 1/20
