Question

tính

\(1,25:\dfrac{15}{20}+\left(25\%-\dfrac{5}{6}\right);4\dfrac{2}{3}\)

Answer 1

\(1,25:\dfrac{15}{20}+\left(25\%-\dfrac{5}{6}\right):4\dfrac{2}{3}\)

\(=\dfrac{5}{4}.\dfrac{4}{3}+\left(\dfrac{1}{4}-\dfrac{5}{6}\right).\dfrac{3}{14}\)

\(=\dfrac{5}{3}+\dfrac{7}{12}.\dfrac{3}{14}\)

\(=\dfrac{5}{3}+-\dfrac{1}{8}\)

\(=\dfrac{37}{24}\)

Answer 2

\(1,25:\dfrac{15}{20}+\left(25\%-\dfrac{5}{6}\right):4\dfrac{2}{3}\)

\(=\dfrac{5}{4}:\dfrac{3}{4}+\left(\dfrac{1}{4}-\dfrac{5}{6}\right):\dfrac{14}{3}\)

\(=\dfrac{5}{4}.\dfrac{4}{3}+\left(\dfrac{-7}{12}\right).\dfrac{3}{14}\)

= \(\dfrac{5}{3}-\dfrac{1}{8}=\dfrac{37}{24}\)
