Question

решите уравнения:
3-(2/9 м + 1/6)=м/3 +1,5

Answer 1

3 - (2/9m + 1/6) = m/3 + 1,5
3 - 2/9m - 1/6 = 1/3m + 1,5
- 2/9m - 1/3m = 1,5 - 3 + 1/6
- 2/9m - 3/9m = - 1,5 + 1/6
- 5/9m = 1/6 - 15/10
- 5/9m = 5/30 - 45/30
- 5/9m = - 40/30 = - 4/3
m = - 4/3 : (- 5/9)
m = - 4/3 * (- 9/5)
m = 12/5 = 2 2/5 
m = 2,4 - в десятичных дробях
