Question

giúp mình giải bài toán này với mình đang cần gấp lắm nhớ giải đầy đủ từng bước giúp mình nha thank you very much

\(\frac{3}{4}-\frac{-5}{9}-\frac{11}{36}\)   

\(\frac{1}{9}+\frac{-5}{3}-\frac{13}{18}\)

Answer 1

\(\frac{3}{4}\)-\(\frac{-5}{9}\)-\(\frac{11}{36}\)=\(\frac{27}{36}\)-\(\frac{-20}{36}\)-\(\frac{11}{36}\)=1

\(\frac{1}{9}\)+\(\frac{-5}{3}\)-\(\frac{-13}{18}\)=\(\frac{2}{18}\)+\(\frac{-30}{18}\)-\(\frac{-13}{18}\)=\(\frac{-15}{18}\)=\(\frac{-5}{6}\)

Answer 2

\(\frac{3}{4}-\frac{-5}{9}-\frac{11}{36}=\frac{27}{36}-\frac{-20}{36}-\frac{11}{36}=\frac{47}{36}-\frac{11}{36}=\frac{36}{36}=1\)

\(\frac{1}{9}+\frac{-5}{3}-\frac{13}{18}=\frac{2}{18}+\frac{-30}{18}-\frac{13}{18}=\frac{-28}{18}+\frac{13}{18}=\frac{-15}{18}=\frac{-5}{6}\)
