Question

прошу помогите!!!!!!!!!!!!!!​

Answer 1

(4,23-2,34)/21=0,09

4,23-2,34=1,89

1,89/21=0,09

(7,13+9,25)/13=1,26

7,13+9,25=16,38

16,38/13=1,26

(50-8,6)/92=0,45

50-8,6=41,4

41,4/92=0,45

(28,88+35,8)/28=2,31

28,88+35,8=64,68

64,68/28=2,31

Answer 2

1) ( 4, 23 - 2, 34 ) ÷ 21 = 0 ,09

2 ) ( 7, 13 + 9,25 ) ÷ 13 = 1, 26

3) ( 50 - 8,6 ) ÷ 92 = 0, 45

4) 28, 88 + 35,8 ) ÷ 28 = 2,31
