Question

thực hiện phép tính

a)\(\frac{9}{18}-\frac{-7}{12}+\frac{13}{32}\)

Answer 1

\(=\frac{13}{12}+\frac{13}{32}\)

\(\frac{143}{96}\)

Answer 2

\(\frac{9}{18}-\frac{-7}{12}+\frac{13}{32}\)

\(=\frac{1}{2}+\frac{7}{12}+\frac{13}{32}\)

\(=\frac{6}{12}+\frac{7}{12}+\frac{13}{32}\)

\(=\)\(\frac{13}{12}+\frac{13}{32}\)

\(=\frac{143}{96}\)

Answer 3

\(a,\frac{9}{18}-\frac{-7}{12}+\frac{13}{32}\)

\(=\frac{6}{12}+\frac{7}{12}+\frac{13}{32}\)

\(=\frac{104}{96}+\frac{39}{96}=\frac{143}{96}\)

mk giải thik cho mak hỉu nhé:

\(\frac{9}{18}=\frac{1}{2}=\frac{6}{12}\)

Answer 4

a) \(\frac{9}{18}-\frac{-7}{12}+\frac{13}{32}\)

\(=\frac{1}{2}+\frac{7}{12}+\frac{13}{32}\)

\(=\frac{48}{96}+\frac{56}{96}+\frac{39}{96}\)

\(=\frac{48+56+39}{96}\)

\(=\frac{143}{96}\)
