Question

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

Answer 1

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


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



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