Question

5/12 - 3/-16 +3/4

giúp mình với 

Answer 1

`5/12-3/(-16)+3/4`

`=5/12-(-3/16)+3/4`

`=5/12+3/16+3/4`

`=20/48+9/48+36/48`

`=29/48+36/48`

`=65/48`

Answer 2

\(\dfrac{5}{12}-\dfrac{3}{-16}+\dfrac{3}{4}\)

\(=\dfrac{5}{12}-\dfrac{-3}{16}+\dfrac{3}{4}\)

\(=\dfrac{80}{192}-\dfrac{-36}{192}+\dfrac{3}{4}\)

\(=\dfrac{29}{48}+\dfrac{3}{4}\)

\(=\dfrac{29}{48}+\dfrac{36}{48}\)

\(=\dfrac{65}{48}\)

Answer 3

\(\dfrac{5}{12}-\dfrac{3}{-16}+\dfrac{3}{4}\)

\(=\dfrac{5}{12}+\dfrac{3}{16}+\dfrac{3}{4}\)

\(=\dfrac{20}{48}+\dfrac{9}{48}+\dfrac{36}{48}\)

\(=\dfrac{65}{48}\)
