1) 36/2= x/5
Решение:
36/2 = x/5
18 = x/5
18*5 = x
90 = x
Ответ: x = 90
2) 18/x = 5/2
Решение:
18/x = 5/2
182 = 5x
36 = 5*x
x = 36/5
x = 7.2
Ответ: x = 7.2
3) 9.9/x = 66/2
Решение:
9.9/x = 66/2
9.9/x = 33
9.9 = 33x
x = 9.9/33
x = 0.3
Ответ: x = 0.3
4) 8.1/0.9 = 3.6/x
Решение:
8.1/0.9 = 3.6/x
9 = 3.6/x
3.6 = 9x
x = 3.6/9
