Question

5 phần 2 - 7 phần 6 : 7 phần 4

Answer 1

\(\dfrac{5}{2}-\dfrac{7}{6}:\dfrac{7}{4}=\dfrac{5}{2}-\dfrac{7}{6}\times\dfrac{4}{7}=\dfrac{5}{2}-\dfrac{4}{6}=\dfrac{30}{12}-\dfrac{8}{12}=\dfrac{22}{12}=\dfrac{11}{6}\)

Answer 2

\(\dfrac{5}{2}-\dfrac{7}{6}:\dfrac{7}{4}\)=\(\dfrac{5}{2}-\dfrac{2}{3}=\dfrac{11}{6}\)

Answer 3

\(=\dfrac{5}{2}-\dfrac{7}{6}\cdot\dfrac{4}{7}=\dfrac{5}{2}-\dfrac{2}{3}=\dfrac{15-4}{6}=\dfrac{11}{6}\)
