Question

2 1/15-3/4m=59/60 решите уравнение

Answer 1

3/4 m = 2 1/15 - 59/60
3/4 m = 31/15 - 59/60
3/4 m = 124/60 - 59/60
3/4 m = 65/60
m =65/60 : 3/4
m = 65/45 = 13/9
m = 1 4/9

Answer 2

2 1/15-3/4m=59/60
3/4m=2 1/15-59/60
3/4m=13/12
m=13/12:3/4
m=13/9
2 1/15-3/4*13/9=31/15-13/12=124/60-65/60=59/60
