ai giống mk thì tích mk nhé

 chuẩn luôn ha

89*| 25+74+1|

sau đo làm như thường nhé

89/16+25(9/16÷125/64)÷(-27/8)

= \(\frac{89}{16}+25\left(\frac{9}{16}:\frac{125}{64}\right):-\frac{27}{8}\)

=\(\frac{89}{16}+\frac{25.36}{125}:-\frac{27}{8}\)

=\(\frac{89}{16}-\frac{32}{15}=\frac{823}{240}\)

\(\frac{89}{16}+25.\left(\frac{9}{16}:\frac{125}{64}\right):\left(\frac{-27}{8}\right)\)

=\(\frac{89}{16}+25.\frac{36}{125}:\left(\frac{-27}{8}\right)\)

=\(\frac{89}{16}+\frac{36}{5}:\left(\frac{-27}{8}\right)\)

=\(\frac{89}{16}+\left(\frac{-32}{15}\right)\)

=\(\frac{823}{240}\)

\(\frac{89}{16}+25\cdot\left(\frac{9}{16}:\frac{125}{64}\right):\left(-\frac{27}{8}\right)\)

\(=\frac{89}{16}+25\cdot\frac{36}{125}:\left(-\frac{27}{8}\right)\)

\(=\frac{89}{16}+7\frac{1}{5}:\left(-\frac{27}{8}\right)\)

\(=\frac{89}{16}-2\frac{2}{15}\)

\(=3\frac{103}{240}\)
