Question

(1/3+0,5+0,25):(2/3+5/12) подробное решение

Answer 1

$frac{ frac{1}{3} + frac{1}{2} + frac{25}{100} }{ frac{2}{3}+ frac{5}{12} } = frac{ frac{1}{3} + frac{1}{2} + frac{1}{4} }{ frac{2}{3}+ frac{5}{12} } = frac{ frac{4}{12} + frac{6}{12} + frac{3}{12} }{ frac{8}{12}+ frac{5}{12} } = \ frac{13}{12} : frac{13}{12} = frac{13}{12} * frac{12}{13} = 1$
