\(\frac{2}{3}+\frac{1}{2}-\frac{5}{3}=\frac{1}{2}-1=-\frac{1}{2}\)
\(\frac{7}{18}-\frac{7}{16}-\frac{11}{32}=\frac{7}{18}-\frac{25}{32}=-\frac{133}{288}\)
-1+1/2=-1/2
7/18-(14/32+11/32)=7/18-25/32=-113/288
\(\frac{2}{3}+\frac{1}{2}-\frac{5}{3}\)
\(=\frac{4}{6}+\frac{3}{6}-\frac{10}{6}\)
\(=\frac{7}{6}-\frac{10}{6}\)
\(=-\frac{3}{6}=-\frac{1}{2}\)
\(\frac{2}{3}+\frac{1}{2}-\frac{5}{3}\)
\(=\frac{4}{6}+\frac{3}{6}-\frac{5}{3}\)
\(=\frac{7}{6}-\frac{10}{6}\)
\(=\frac{-3}{6}=\frac{-1}{2}\)
\(\frac{2}{3}+\frac{1}{2}-\frac{5}{3}\)
\(=\frac{4}{6}+\frac{3}{6}-\frac{10}{6}\)
\(=-\frac{3}{6}=-\frac{1}{2}\)
\(\frac{7}{18}-\frac{7}{16}-\frac{11}{32}\)
\(=\frac{112}{288}-\frac{126}{288}-\frac{99}{288}\)
\(=\frac{112-126-99}{288}\)
\(=-\frac{113}{288}\)
Good luck !!! Rất vui vì giúp đc bạn <3
2/3+1/2-5/3
=1 và 1/6-5/3
=-1/2
7/18-7/16-11/32
=-7/144-11/32
=-113/288
Chúc bn học tốt
