Question

2*3*8/4*5*6*7

mọi người giải hộ mình nhé

Answer 1

\(=\dfrac{2\cdot3\cdot8}{4\cdot6\cdot5\cdot7}=\dfrac{6\cdot8}{4\cdot6\cdot5\cdot7}=\dfrac{2}{35}\)

Answer 2

`[2xx3xx8]/[4xx5xx6xx7]`

`=[6xx4xx2]/[4xx6xx5xx7]`

`=2/[5xx7]=2/35`

Answer 3

\(=\dfrac{2.3.4.2}{4.6.2.3.7}=\dfrac{2}{6.7}=\dfrac{2}{42}\)
