Question

Tính:

a) \(\dfrac{5}{6}-\dfrac{4}{6}\)                      b) \(\dfrac{7}{12}-\dfrac{6}{12}\)                    c) \(\dfrac{7}{9}-\dfrac{2}{9}\)                       d) \(\dfrac{16}{5}-\dfrac{9}{5}\)

Answer 1

a: \(\dfrac{5}{6}-\dfrac{4}{6}=\dfrac{5-4}{6}=\dfrac{1}{6}\)

b: \(\dfrac{7}{12}-\dfrac{6}{12}=\dfrac{7-6}{12}=\dfrac{1}{12}\)

c: \(\dfrac{7}{9}-\dfrac{2}{9}=\dfrac{7-2}{9}=\dfrac{5}{9}\)

d: \(\dfrac{16}{5}-\dfrac{9}{5}=\dfrac{16-9}{5}=\dfrac{7}{5}\)
