Question

Помогите решить уравнение 2 1/15-3/4m = 59/60 пожалуйста

Answer 1

$2 \frac{1}{15} - \frac{3}{4} m = \frac{59}{60} \\ \frac{3}{4} m = 2 \frac{1}{15} - \frac{59}{60} \\ \frac{3}{4} m = 2 \frac{2}{60} - \frac{59}{60} = 1 \frac{62}{60} - \frac{59}{60} \\ \frac{3}{4} m = 1 \frac{3}{60} = 1 \frac{1}{20} \\ m = \frac{21}{20} \div \frac{3}{4} \\ m = \frac{7}{5} = 1 \frac{2}{5}$

Answer 2

2 1/15-3/4m = 59/60
-3/4m =2 1/15-59/60
-3/4m =2 4/60-59/60
-3/4 m=1 5/60
m=1 5/60:(-3/4)
m=65/60*4/3
m=65/15*1/3
m=65/45=1 20/45

Проверка:3/4*1 20/45=3/4*65/45=65/60=
=1 5/60
2 1/15-1 5/60=2 4/60-1 5/60=1 64/60-1 5/60=59/60
