Cho mk hỏi bạn có chép sai đầu bài ko

Olm chào em, em nên viết đề bài bẳng công thức toán học, em nhé.

\(\frac{34}{11}\cdot\frac{27}{46}\cdot\frac{23}{17}\cdot\frac{22}{9}\)

\(=\frac{34\cdot27\cdot23\cdot22}{11\cdot46\cdot17\cdot9}\)

\(=\frac{2\cdot17\cdot3\cdot3\cdot3\cdot23\cdot2\cdot11}{11\cdot2\cdot23\cdot17\cdot3\cdot3}\)

\(=\frac{3\cdot2}{1}\)

\(=6\)

=))

\(\frac{34}{11}x\frac{27}{46}x\frac{23}{17}x\frac{22}{9}\)

= 2/1 x 3/2 x 1/1 x 2/1

= 6

\(3\frac{3}{11}x27\frac{27}{46}x1\frac{6}{17}x2\frac{4}{9}=\frac{34x1269x23x22}{11x46x17x9}=\frac{2x17x141x9x23x2x11}{11x23x17x9}=282\)

\(25\frac{2}{13}-\left(\frac{15}{17}+15\frac{2}{3}\right)=\frac{327}{13}-\left(\frac{15}{17}+\frac{47}{3}\right)\)

\(=\frac{327}{13}-\frac{844}{51}\)

\(=\frac{5705}{663}\)

\(\frac{5}{30}+\frac{15}{90}+\frac{250}{150}+\frac{350}{210}+\frac{45}{270}=\frac{1}{6}+\frac{1}{6}+\frac{5}{3}+\frac{5}{3}+\frac{1}{6}\)

\(=\frac{3}{6}+\frac{10}{3}\)

\(=\frac{1}{2}+\frac{10}{3}\)

\(=\frac{23}{6}\)

\(3\frac{1}{11}.\frac{27}{46}.1\frac{6}{17}.2\frac{4}{9}=\frac{34}{11}.\frac{27}{46}.\frac{23}{17}.\frac{22}{9}\)

\(=\frac{68}{9}.\frac{27}{34}\)

\(=6\)
