\(\frac{\frac{15}{6.16}+\frac{15}{16.26}+\frac{15}{26.36}}{\frac{33}{6.16}-\frac{63}{16.26}-\frac{93}{26.36}}\)
\(=\frac{\frac{15}{10}\cdot\left(\frac{1}{6}-\frac{1}{16}+\frac{1}{16}-\frac{1}{26}+\frac{1}{26}-\frac{1}{36}\right)}{\frac{11}{32}-\frac{63}{416}-\frac{31}{312}}\)
\(=\frac{\frac{15}{10}\cdot\left(\frac{1}{6}-\frac{1}{36}\right)}{\frac{143}{416}-\frac{63}{416}-\frac{124}{\frac{3}{416}}}=\frac{\frac{5}{24}}{\frac{143-63-\frac{124}{3}}{416}}\)
\(=\frac{\frac{5}{24}}{\frac{116}{\frac{3}{416}}}=\frac{\frac{5}{24}}{\frac{29}{312}}=\frac{65}{29}\)
nếu phần cuối giống như trên thì bạn nào biết làm ko
