Пожалуйста помогите, очень нужно!!!! ​

Answer 1

Ответ:

Пошаговое объяснение:

1) 1.8 * 3 = 5.4

1.8/3 = 0.6

2) 0.6 * 0.2 = 0.12

0.6 / 0.2 = 3

3) a = 9.8 / 7 = 1.4

1.4/7 = 0.2

4) b =  0.05

5/0.05 = 100

5) b = 0.12 / 0,02 = 6

0.12 * 6 = 0.72

6) a = 3 * 1.5 = 4.5

4.5 * 3 = 13.5

Answer 2

1. а* b = 1.8*3 =5.4

  a: b =  1.8 :3 = 0.6

2.  0.6 * 0.2 = 0.12

    0.6 : 0.2 = 3

3. a * 7 = 9.8

   a = 9.8:7 = 1.4

   1.4: 7 = 0.2

4. b = 0.25:5 = 0.05

  5: 0.05 = 100

5.  0.12:b = 0.02

   b = 6

  0.12 * 6 = 0.72

6. a * 3 = 1.5

 a = 0.5

0.5 * 3 = 1.5
