Question

Помогите решить уравнение: 1) z - 1 3|4=2 7|12;2) m - 7 1/9=2 5/36; n - 10 7|12= 3 1|6

Answer 1

1)
$z-1 frac{3}{4} =2 frac{7}{12}$
$z=2 frac{7}{12} +1 frac{3}{4}$
$z=2 frac{7}{12} +1 frac{9}{12}$
$z=3 frac{16}{12}$
$z=4 frac{1}{3}$
===========
2)
$m-7 frac{1}{9} =2 frac{5}{36}$
$m=2 frac{5}{36} +7 frac{1}{9}$
$m=2 frac{5}{36} +7 frac{4}{36}$
$m=9 frac{9}{36}$
$m=9 frac{1}{4}$
==============
3)
$n-10 frac{7}{12} =3 frac{1}{6}$
$m=3 frac{1}{6} +10 frac{7}{12}$
$m=3 frac{2}{12} +10 frac{7}{12}$
$m=13 frac{9}{12}$
$m=13 frac{3}{4}$
