Question

tinh nhanh (5/12+1/2x1/3):(2x1/3-1x1/12) giup mình

Answer 1

\(\left(\frac{5}{12}+\frac{1}{2}\times\frac{1}{3}\right):\left(2\times\frac{1}{3}-1\times\frac{1}{12}\right)\)

\(=\left(\frac{5}{12}+\frac{1}{6}\right):\left(\frac{2}{3}-\frac{1}{12}\right)\)

\(=\frac{7}{12}:\frac{7}{12}\)

\(=1\)
