Question

Решите, пожалуйста (1 пример)

Answer 1

1) 3 1/3 + 2,5 = 10/3 + 5/2 = 20/6 + 15/6 = 35/6
2) 2,5 - 1 1/3 = 5/2 - 4/3 = 15/6 - 8/6 = 7/6
3) 35/6 : 7/6 = 35/6 * 6/7 = 5

4) 4,6 - 2 1/3 = 23/5 - 7/3 = 69/15 - 35/15 = 34/15
5) 4,6 + 2 1/3 = 23/5 + 7/3 = 69/15 + 35/15 = 104/15
6) 34/15 : 104/15 = 34/15 * 15/104 = 17/52

7) 5 * 17/52 = 85/52

8) 85/52 * 5,2 = 85/52 * 52/10 = 85/10 = 8,5

9) 1/7 - 0,125 =1/7 - 1/8 = 8/56 - 7/56 = 1/56

10) 0.05 : 1/56 = 1/20 * 56 = 56/20 = 14/5 = 2,8

11) 2,8 + 5,7 = 8,5

12) 8,5: 8,5 = 1

ответ : 1

Answer 2

1)3 1/3+2 1/2=3 2/6+2 3/6=5 5/6
2)2 1/2-1 1/3=2 3/6-1 2/6=1 1/6
3)5 5/6:1 1/6=35/6:7/6=35/6*6/7=5
------------------------
4)4 6/10-2 1/3=4 18/30-2 10/30=5 8/30=2 4/15
5)4 6/10+2 1/3=4 18/30+2 10/30=6 28/30=6 14/15
6)2 4/15:6 14/15=34/15*15/104=17/52
7)5(17/52=85/52
8)85/52*5,2=85/52*52/10=8,5
------------------------
9)1/7-1/8=8/56-7/56=1/56
10)1/20:1/56=56/20=2,8
11)2,8+5,7=8,5
-----------------------------
12)8,5:8,5=1
