(524м+1718):13=3 23 решите уравнение,иииии х:78=849:87

Answer 1

$( frac{5}{24}m+frac{17}{18}):frac{1}{3} =frac{11}{3} |*1/3\ frac{5}{24}m+frac{17}{18}=frac{11}{9}\ frac{5}{24}m=frac{5}{18}\ m=frac{5}{18}*frac{24}{5}\ m=frac{4}{3}$

$x: frac{7}{8}= frac{8}{49} : frac{8}{7} \ x: frac{7}{8} = frac{8*7}{49*8} \ x: frac{7}{8}=frac{1}{2}\ x= frac{7}{16}$
