Question

27:(31 3/7х-2 11/14х)=1 1/8

Answer 1

$27:(31frac{3}{7x}-2frac{11}{14x})=1frac{1}{8}$

$31frac{3}{7x}-2frac{11}{14x}=27:1frac{1}{8}$

$frac{220}{7x}-frac{39}{14x}=27:frac{9}{8}$

$frac{440-39}{14x}=27cdotfrac{8}{9}$

$frac{401}{14x}=24$

$14x=frac{401}{24}$

$x=frac{401}{24}:14=frac{401}{24}cdotfrac{1}{14}=frac{401}{336}=1frac{65}{336}$
