Tính nhanh:

P=\(\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{3}{12}+1+\frac{7}{11}}\)

Answer 1

[Vũ Ngọc Hải Đăng]

\(P=\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{3}{12}+1+\frac{7}{11}}\)

\(P=\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{1}{4}+1+\frac{7}{11}}\)

\(P=\frac{\left(\frac{2}{3}-\frac{1}{4}+\frac{5}{11}\right)\cdot132}{\left(\frac{1}{4}+1+\frac{7}{11}\right)\cdot132}\)

\(P=\frac{88-33+60}{33+132+84}\)

\(P=\frac{115}{249}\)
