Question

Tính:
12/17: 4 x 1/4.

Answer 1

`12/17:4xx1/4`

`=12/17xx1/4xx1/4`

`=12/68xx1/4`

`=(12xx1)/(68xx4)`

`=(3xx1)/(68xx1)`

`=3/68`

Answer 2

\(\dfrac{12}{17}:4\times\dfrac{1}{4}\)
\(=\dfrac{12}{17}\times\dfrac{1}{4}\times\dfrac{1}{4}\)
\(=\dfrac{12}{272}=\dfrac{3}{68}\)

Answer 3

\(\dfrac{12}{17}\)\(:4\) x \(\dfrac{1}{4}\)

= \(\dfrac{12}{17}\) x \(\dfrac{1}{4}\) x \(\dfrac{1}{4}\)

= \(\dfrac{12}{272}\) = \(\dfrac{3}{68}\)
