3/12  x  3 - 4/8

Giúp mình nha

Answer 1

[Vu Tran]

\(362009dm^3=362009000m^3\)

\(\frac{3}{12}\times3-\frac{4}{8}\)

\(=\frac{3}{4}-\frac{4}{8}=\frac{6}{8}-\frac{4}{8}=\frac{2}{8}=\frac{1}{4}\)

Answer 2

[Sylveon]

632009 dm³ = 632,009 m³

\(\frac{3}{12}\cdot3-\frac{4}{8}=\frac{1}{4}\cdot3-\frac{1}{2}=\frac{3}{4}-\frac{1}{2}=\frac{3}{4}-\frac{2}{4}=\frac{1}{2}\)
