Answer 2

Answer : $\bold{7/4}$


Explanation -


Let the number is x


According to the given question -


$(x - \dfrac{1}{2} ) \times 4 = 5$



$( \dfrac{2x - 1}{2} ) \: 4 = 5$


$\dfrac{8x - 4}{2} = 5$


$8x - 4 = 10$


$8x = 10 + 4$


$8x = 14$


$x = \dfrac{14}{8}$


Simplifying by 2


$\dfrac{14}{8} = \dfrac{7}{4}$



Hence :

$\bold{Answer : 7/4}$
