Answer 2

Answer :

To find :

• The missing number.

Solution :

Let the number be x

Substituting the values in formula :

➦ $\dfrac{4}{5} + (-x) = \dfrac{23}{10}$

➦ $\dfrac{4}{5} -x = \dfrac{23}{10}$

➦ $-x = \dfrac{23}{10} - \dfrac{4}{5}$

➦ $-x = \dfrac{23-8}{10}$

➦ $-x = \dfrac{15}{10}$

➦ $-x = \dfrac{3}{2}$

➦ $x = \dfrac{-3}{2}$

•°• Thus the value of x is -3/2
