Question

всем привет помогите решить уравнение:10 4/5:х-2 2/3=1 5/6

Answer 1

Ответ:

Пошаговое объяснение:

10. 4/5 : х - 2. 2/3 = 1. 5/6

10. 4/5 : х = 1. 5/6 + 2. 2/3

10. 4/5 : х = 1. 5/6 + 2. 4/6

10. 4/5 : х = 3. 9/6

10. 4/5 : х = 4. 3/6

10. 4/5 : х = 4. 1/2

54/5 : х = 9/2

х = 54/5 : 9/2

х = 54/5 * 2/9

х = 6/5 * 2/1

х = 12/5

х = 2. 2/5 или 2,4

Answer 2

Ответ:

10 4/5:х-2 2/3=1 5/6

$10\frac{4}{5} :x-2\frac{2}{3}=1\frac{5}{6}\\\\\frac{10*5+4}{5} *\frac{1}{x} -\frac{3*2+2}{3}=\frac{6*1+5}{6} \\\\\frac{54}{5x}-\frac{8}{3} =\frac{11}{6}\\\\\frac{54}{5x} =\frac{11}{6}+\frac{8}{3} \\\\\frac{54}{5x} = \frac{11+16}{6} \\\\\frac{54}{5x} = \frac{27}{6} \\\\\frac{54}{5x} = \frac{9}{2}\\\\54*2=5x*9\\\\108=45x; 45x=108 \\\\x=\frac{108}{45}=\frac{12}{5}=2\frac{2}{5}=2,4$
