Question

\(\frac{-5}{18}+\frac{5}{9}-\frac{11}{36}\)

\(\frac{-39}{44}\div1\frac{2}{11}\)

\(\frac{-7}{11}.\frac{11}{19}+\frac{-7}{11}.\frac{8}{19}+\frac{-4}{11}\)

Answer 1

\(\frac{-5}{18}+\frac{5}{9}-\frac{11}{36}\)

\(=\frac{-10}{36}+\frac{20}{36}-\frac{11}{36}\)

\(=-\frac{1}{36}\)

vậy_

Answer 2

\(\frac{-5}{18}+\frac{5}{9}-\frac{11}{36}\)

\(=\frac{5}{18}-\frac{11}{36}\)

\(=\frac{-1}{36}\)

___________________________

\(\frac{-39}{44}:1\frac{2}{11}\)

\(=\frac{-39}{44}:\frac{13}{11}\)

\(=\frac{-3}{4}\)

_________________________

\(\frac{-7}{11}.\frac{11}{19}+\frac{-7}{11}.\frac{8}{19}+\frac{-4}{11}\)

\(=\frac{-7}{11}.\left(\frac{11}{19}+\frac{8}{19}\right)+\frac{-4}{11}\)

\(=\frac{-7}{11}.1+\frac{-4}{11}\)

\(=\frac{-7}{11}+\frac{-4}{11}\)

\(=\frac{-11}{11}=-1\)

Answer 3

\(\frac{-5}{18}+\frac{5}{9}-\frac{11}{36}\)

\(=\frac{-10}{36}+\frac{20}{36}-\frac{11}{36}\)

\(=\frac{-1}{36}\)

\(\frac{-7}{11}.\frac{11}{19}+\frac{-7}{11}.\frac{8}{19}+\frac{-4}{11}\)

\(=\frac{-3}{4}\)

Answer 5

a,\(-\frac{5}{18}+\frac{5}{9}-\frac{11}{36}=-\frac{5}{18}+\frac{10}{18}-\frac{11}{36}\)

\(=\frac{10}{36}-\frac{11}{36}=-\frac{1}{36}\)

b,\(\frac{-39}{44}:1\frac{2}{11}=\frac{-39}{44}:\frac{13}{11}\)

\(=\frac{-39}{44}.\frac{11}{13}=-\frac{3}{4}\)

c,\(\frac{-7}{11}.\frac{11}{19}+\frac{-7}{11}.\frac{8}{19}+\frac{-4}{11}\)

\(=-\frac{7}{11}\left(\frac{11}{19}+\frac{8}{19}\right)+\frac{-4}{11}\)

\(=\frac{-7}{11}+\frac{-4}{11}=-1\)
