Question

VD: 2 3/4: Hai ba phần bốn

-----------------

(45 1/2 - 2 3/8)-(5 5/6+6 3/4) +(10 2/3-5 5/8)

Ai giải hộ mình với ;;^;;

Answer 1

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

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

\(=\frac{345}{8}-\frac{151}{12}+\frac{121}{24}\)

\(=\frac{1035}{24}-\frac{302}{24}+\frac{121}{24}\)

\(=\frac{854}{24}\)\(=\frac{427}{12}\)
