tính nhanh:\(\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}+1-\frac{7}{11}}\)
tính nhanh: P=\(\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}+1-\frac{7}{11}}\)
\(P=\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}+1-\frac{7}{11}}\)
\(\Rightarrow P=\frac{\frac{8}{12}-\frac{3}{12}+\frac{5}{11}}{\frac{5}{12}+\frac{11}{11}-\frac{7}{11}}\)
\(\Rightarrow P=\frac{\frac{5}{12}+\frac{5}{11}}{\frac{5}{12}+\frac{4}{11}}\)
Chúc bạn học tốt !!!
Tính nhanh: P=\(\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}-1-\frac{7}{11}}\)

Tính nhanhHọc nhiều quá quên mất bài dễ này rồi
Tính nhanh
P= \(\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}+1-\frac{7}{11}}\)
Tính nhanh:\(P=\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}+1-\frac{7}{11}}\)
Tính nhanh \(P=\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}+1-\frac{7}{11}}\)
\(\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}+1-\frac{7}{11}}=\frac{3.4.11\left(\frac{2}{3}-\frac{1}{4}+\frac{5}{11}\right)}{3.4.11\left(\frac{5}{12}+1-\frac{7}{11}\right)}=\frac{88-33+60}{55+132-84}=\frac{115}{103}\)
Tính nhanh:\(P=\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}+1-\frac{7}{11}}\)
Tính nhanh\(y=\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}+1-\frac{7}{11}}\)
Tính nhanh:
P=\(\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{3}{12}+1+\frac{7}{11}}\)
\(P=\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{3}{12}+1+\frac{7}{11}}\)
\(P=\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{1}{4}+1+\frac{7}{11}}\)
\(P=\frac{\left(\frac{2}{3}-\frac{1}{4}+\frac{5}{11}\right)\cdot132}{\left(\frac{1}{4}+1+\frac{7}{11}\right)\cdot132}\)
\(P=\frac{88-33+60}{33+132+84}\)
\(P=\frac{115}{249}\)
