673. Решите уравнения: 1) x: 5,8 = 365;
3) x: 8,1 = 0,15;
2) x : 8,4 = 2,3;
4) x: 0,22 = 4,9.​

1 ) x: 5.8 = 365

Step-by-step explanation:

x = 365 × 5.8

x = 2117

2117: 5.8 = 365

2) x: 8.4 = 2.3

x = 2.3 × 8.4

x = 19.32

19.32: 8.4 = 2.3

3) x: 8.1 = 0.15

x = 0.15 X 8.1

x = 1.215

1.215: 8.1 = 0.15

4) x: 0.22 = 4.9

x = 4.9 x 0.22

x = 1.078

1.078: 0.22 = 4.9
