Verified answer

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

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

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