\(5487+8369=13856\)

\(37978-5169=32809\)

\(4\) x \(\dfrac{7}{4}=\dfrac{\text{4 x 7}}{4}=\dfrac{28}{4}=7\) 

\(\dfrac{6}{11}:\dfrac{3}{4}=\dfrac{6}{11}\) x \(\dfrac{4}{3}=\dfrac{24}{33}=\dfrac{8}{11}\)

Answer 2

[Phạm Ngọc Khánh Linh]

5487 + 8369 = 13 856

37 978 - 5169 = 32 809

4 x \(\dfrac{7}{4}\) = \(\dfrac{28}{4}\) = 7

\(\dfrac{6}{11}:\dfrac{3}{4}=\dfrac{6}{11}x\dfrac{4}{3}=\dfrac{24}{33}=\dfrac{8}{11}\)
