Решите уравнение 4)m-7 1/9 = 2 5/36 5)n-10 7/12 = 3 1/6 6)R-6 1/7 = 1 5/14

Решите задачу:

$m-7 \frac{1}{9}=2 \frac{5}{36} \\\\ m= 2\frac{5}{36}+ 7 \frac{1}{9}\\\\ m= \frac{77}{36}+ \frac{64}{9}\\\\ m= \frac{77+256}{36}\\\\ m= \frac{333}{36} \\\\ m=9 \frac{1}{4}$

$n-10 \frac{7}{12}=3 \frac{1}{6}\\\\ n= 3 \frac{1}{6}+10 \frac{7}{12}\\\\ n= \frac{19}{6}+ \frac{127}{12}\\\\ n= \frac{38+127}{12} \\\\ n= \frac{165}{12}\\\\ n=13 \frac{3}{4}$

$R-6 \frac{1}{7}=1 \frac{5}{14}\\\\ R= 1 \frac{5}{14}+6 \frac{1}{7}\\\\ R= \frac{19}{14}+ \frac{43}{7}\\\\ R= \frac{19+86}{14} \\\\ R= \frac{105}{14}\\\\ R=7 \frac{1}{2}$
