bằng bao nhiêu ?

trình bày cách làm 

Answer 1

\(2\frac{1}{3}:3\frac{1}{4}\)

\(=\frac{7}{3}:\frac{13}{4}\)

\(=\frac{28}{39}\)

Answer 2

=7/3:13/4

=7/3*4/13=28/39

Answer 3

\(2\frac{1}{3}\div3\frac{1}{4}\)

\(=\frac{7}{3}\div\frac{13}{4}\)

\(=\frac{7}{3}\times\frac{4}{13}\)

\(=\frac{28}{39}\)

Answer 4

\(2\frac{1}{3}:3\frac{1}{4}=\frac{7}{3}:\frac{13}{4}=\frac{7}{3}.\frac{4}{13}=\frac{28}{39}\)

Answer 5

\(2\frac{1}{3}:3\frac{1}{4}\)

= \(\frac{7}{3}:\frac{13}{4}\)

\(\frac{7x4}{3x13}=\frac{28}{39}\)

Answer 6

\(2\frac{1}{3}\):\(3\frac{1}{4}\)

=\(\frac{7}{3}\):\(\frac{13}{4}\)

=\(\frac{7\cdot4}{3\cdot4}\):\(\frac{13\cdot3}{4\cdot3}\)

=\(\frac{28}{12}\):\(\frac{39}{12}\)

=\(\frac{28}{12}\)x\(\frac{12}{39}\)

=\(\frac{28}{39}\)
