Question

\(A=\frac{\frac{1}{4}+\frac{1}{5}+\frac{1}{6}}{\left(\frac{1}{4}+\frac{1}{5}-\frac{1}{6}\right)-\frac{1}{4}.\frac{1}{5}.\frac{1}{6}}\)

Answer 1

Ta có \(A=\frac{\frac{1}{4}+\frac{1}{5}+\frac{1}{6}}{\left(\frac{1}{4}+\frac{1}{5}-\frac{1}{6}\right)-\frac{1}{4.5.6}}=\frac{\frac{\left(15+12+10\right)}{60}}{\left(\frac{15+12-10}{60}\right)-\frac{1}{120}}\)\(=\frac{\frac{37}{60}}{\frac{27}{60}-\frac{1}{120}}=\frac{37}{60}:\frac{54}{120}=\frac{37}{60}.\frac{120}{54}=\frac{37.2.60}{60.2.37}=1\)

Answer 2

\(\frac{\frac{1}{4}+\frac{1}{5}+\frac{1}{6}}{(\frac{1}{4}+\frac{1}{5}-\frac{1}{6})-\frac{1}{4}.\frac{1}{5}.\frac{1}{6}}\)=\(\frac{\frac{37}{60}}{\frac{17}{60}-\frac{1}{120}}\)=\(\frac{\frac{37}{60}}{\frac{33}{120}}\)=\(\frac{37}{60}:\frac{33}{120}=\frac{37}{60}.\frac{120}{33}\)=\(\frac{74}{33}\)
