Question

tính

\(\left(45\dfrac{1}{2}-2\dfrac{3}{8}\right)\) x \(\left(5\dfrac{5}{6}+6\dfrac{3}{4}\right)\)+ \(\left(10\dfrac{2}{3}-5\dfrac{5}{8}\right)\)

Answer 1

\(=\left(\dfrac{91}{2}-\dfrac{19}{8}\right)\cdot\left(\dfrac{35}{6}+\dfrac{27}{4}\right)+\left(\dfrac{32}{3}-\dfrac{45}{8}\right)\)

\(=\dfrac{345}{8}\cdot\dfrac{151}{12}+\dfrac{121}{24}\)

\(=\dfrac{52579}{96}\)
