1)7/12-3/8
2)4/15+7/12
3)3 1/6+2/3
4)12 3/8+8 1/6

Answer 1

Ответ:

1) 7/12 - 3/8 = 14 - 9/24 = 5/24

2) 4/15 + 7/12 = 16 + 35/60 = 51/60 (сократили на 3 ) = 17/20

3) 3 1/6 + 2/3 = 19/6 + 2/3 = 23/6

4) 12 3/8 + 8 1/6 = (12 + 8) + (3/8 + 1/6) = 20 + 13/24 = 20 13/24

Answer 2

ответ: 1) 7/12-3/8=14-9/24=5/24

2)4/15+7/12=16+35/60=51/60=17/20

3)3 1/6+2/3=19/6+2/3=23/6=3 5/6

4)12 3/8+8 1/6=(12+8)+(3/8+1/6)=20+ 13/24=20 13/24
