Question

Viết phép tính thích hợp với mỗi hình (theo mẫu).

Answer 1

a) \(\dfrac{4}{5}-\dfrac{1}{5}=\dfrac{4-1}{5}=\dfrac{3}{5}\)

b) \(\dfrac{3}{4}-\dfrac{2}{4}=\dfrac{3-2}{4}=\dfrac{1}{4}\)

c) \(\dfrac{5}{5}-\dfrac{2}{5}=\dfrac{5-2}{5}=\dfrac{3}{5}\)

Answer 2

a) \(\dfrac{4}{5}\) - \(\dfrac{1}{5}\) = \(\dfrac{3}{5}\)
b) \(\dfrac{3}{4}\) - \(\dfrac{2}{4}\) = \(\dfrac{1}{4}\)
c)\(\dfrac{5}{5}\) - \(\dfrac{2}{5}\)  = \(\dfrac{3}{5}\)
