Question

3/2 - 4/7 + 1/14 Gải chi tiét nh

Answer 1

`3/2 - 4/7 + 1/14`

`= 21/14 - 8/14 + 1/14`

`= 15/14`

Answer 2

\(\dfrac{3}{2}-\dfrac{4}{7}+\dfrac{1}{14}\)

\(=\dfrac{21}{14}-\dfrac{8}{14}+\dfrac{1}{14}\)

\(=\dfrac{21-8+1}{14}\)

\(=\dfrac{14}{14}\)

\(=1\)

Answer 3

\(\dfrac{21}{14}-\dfrac{8}{14}+\dfrac{1}{14}=\dfrac{14}{14}=1\)

Answer 4

\(\dfrac{3}{2}-\dfrac{4}{7}+\dfrac{1}{14}\)

\(=\dfrac{3}{2}+\left(\dfrac{-4}{7}\right)+\dfrac{1}{14}\)

\(=\dfrac{13}{14}+\dfrac{1}{14}\)

\(=1\)
