Question

a) 12:m -0,2 = 3,8 уравнение помогите решить​

Answer 1

$\displaystyle 12:m-0,2=3,8,m\neq 0\\\\\frac{12}{m}-\frac{1}{5}=3,8\\ \\\frac{12}{m}=3,8+\frac{1}{5}\\ \\\frac{12}{m}=\frac{19}{5}+\frac{1}{5}\\ \\\frac{12}{m}=4\\ \\12=4m\\ 4m=12\\ m=3$

Answer 2

12:m= 3,8+0,2

12: m= 4,0

12:m= 4

m= 12:4

m=3
