Question

2/5 + 3/5 : -3/2 + 1/2

Answer 1

`2/5+3/5:(-3)/2 +1/2`

`=2/5 +3/5 . (-2)/3 +1/2`

`=2/5+(-2)/5+1/2`

`=2/5-2/5+1/2`

`=0+1/2`

`=1/2`

Answer 2

\(=\dfrac{2}{5}-\dfrac{4}{15}+\dfrac{1}{2}\\ =\dfrac{2.6-4.2+15}{30}\\ =\dfrac{19}{30}\)

Answer 3

\(\dfrac{2}{5}+\dfrac{3}{5}:\dfrac{-3}{2}+\dfrac{1}{2}=\dfrac{2}{5}+\dfrac{-2}{5}+\dfrac{1}{2}=0+\dfrac{1}{2}=\dfrac{1}{2}\)

Answer 4

= 2/5 +( -2/5 )+ 1/2

= 0 + 1/2

= 1/2
