Question

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

Answer 1

\(2\dfrac{-3}{4}=\dfrac{5}{4}\)

Answer 2

`2 + (-3/4)`

`= 8/4 + (-3/4)`

`= 5/4`

Answer 3

\(\dfrac{2\times4}{1\times4}+\dfrac{-3}{4}=\dfrac{8}{4}+\dfrac{-3}{4}=\dfrac{5}{4}\)

Answer 4

2 + (-3/4)

= 8/4 + (-3/4)

=8-3/4

=5/4

Answer 5

phân số :
5/4
hỗn số: 1 1/4
thập phân: 1,25

Answer 6

2+\(\dfrac{-3}{4}\)=\(\dfrac{8}{4}\)+\(\dfrac{-3}{4}\)

           =\(\dfrac{8+\left(-3\right)}{4}\)

           =  \(\dfrac{8-3}{4}\)

           =     \(\dfrac{5}{4}\)
