Question

\(\dfrac{1}{3}-\dfrac{1}{-4}-\dfrac{1}{2}\)

nhanh ạ

Answer 1

=1/3+1/4-1/2

=7/12-6/12=1/12

Answer 2

\(\dfrac{1}{3}-\dfrac{1}{-4}-\dfrac{1}{2}\)

 

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

 

\(=\dfrac{4}{12}+\dfrac{3}{12}-\dfrac{6}{12}\)

 

\(=\dfrac{1}{12}\)

Answer 3

`1/3-1/[-4]-1/2=1/3+1/4-1/2=4/12+3/12-6/12=1/12`

Answer 4

\(\dfrac{1}{3}+\dfrac{1}{4}-\dfrac{1}{2}=\dfrac{4}{12}+\dfrac{3}{12}-\dfrac{6}{12}=\dfrac{1}{12}\)

Answer 5

1/3 + 1/4 - 1/2

7/12 - 6/12

1/12
