Question

Answer 1

làm bài 2,4 thôi

Answer 2

B2

2km 58m = 2058m

44 tấn = 44 000 kg

165dm = 16m 5dm

\(\dfrac{3}{5}\)ha= 6 000 m²

B4:

\(a.x:\dfrac{3}{5}=3\dfrac{1}{3}\\ x:\dfrac{3}{5}=\dfrac{10}{3}\\ x=\dfrac{10}{3}\times\dfrac{3}{5}\\ x=2\)

\(b.x:\dfrac{1}{2}=\dfrac{3}{4}+\dfrac{1}{6}\\ x:\dfrac{1}{2}=\dfrac{11}{12}\\ x=\dfrac{11}{12}\times\dfrac{1}{2}\\ x=\dfrac{11}{24}\)
