\(\frac{3}{5}+\frac{3}{11}-\left(\frac{-3}{7}\right)+\frac{2}{97}-\frac{1}{35}-\frac{3}{4}+\frac{22}{44}\)
\(=\frac{3}{5}+\frac{3}{11}+\frac{3}{7}+\frac{2}{97}-\frac{1}{35}-\frac{3}{4}+\frac{22}{44}\)
\(=\frac{3}{5}+\frac{3}{7}-\frac{1}{35}+\frac{3}{11}-\frac{3}{4}+\frac{22}{44}+\frac{2}{97}\)
\(=\left(\frac{3}{5}+\frac{3}{7}-\frac{1}{35}\right)+\left(\frac{3}{11}-\frac{3}{4}+\frac{22}{44}\right)+\frac{2}{97}\)
\(=\left(\frac{21}{35}+\frac{15}{35}-\frac{1}{35}\right)+\left(\frac{12}{44}-\frac{33}{44}+\frac{22}{44}\right)+\frac{2}{97}\)
\(=\frac{35}{35}+\frac{1}{44}+\frac{2}{97}\)
\(=1+\left(\frac{1}{44}+\frac{2}{97}\right)\)
\(=1+\left(\frac{97}{4268}+\frac{88}{4268}\right)\)
\(=1+\frac{185}{4268}=1\frac{185}{4268}\)
Chúc bạn học tốt
Trả lời:
\(\frac{3}{5}+\frac{3}{11}-\left(\frac{-3}{7}\right)+\frac{2}{97}-\frac{1}{35}-\frac{3}{4}+\frac{22}{44}\)
\(=\frac{3}{5}+\frac{3}{11}+\frac{3}{7}+\frac{2}{97}-\frac{1}{35}-\frac{3}{4}+\frac{22}{44}\)
\(=\left(\frac{3}{5}+\frac{3}{7}-\frac{1}{35}\right)+\left(\frac{3}{11}-\frac{3}{4}+\frac{22}{44}\right)+\frac{2}{97}\)
\(=1+\frac{1}{44}+\frac{2}{97}\)
\(=\frac{4453}{4268}\)
3/5+3/11+3/7+2/97-1/35-3/4+22/44
(3/5+3/7-1/35)+(3/11-3/4+22/44)+2/97
(21/35+15/35-1/35)+(12/44-33/44+22/44)+2/97
1+1/44+2/97
4453/4268
