Simplify: $$(\frac 23+\frac13)$$​ × 23 – 13 + 6.

Correct option is B

Given:

​$$(\dfrac{2}{3} + \dfrac{1}{3}) \times 23 - 13 + 6$$​​

Solution:

Simplifying the fraction addition

​$$\frac{2}{3} + \frac{1}{3} = \frac{2+1}{3} = \frac{3}{3} = 1$$ 

then, 

= 1 × 23 − 13 + 6

= 23− 13 + 6

= 10 + 6 

= 16

The simplified value of the expression is 16.

Thus, correct option is (b)
