Question

What should be added to (-9/7+2/3) to get 16/5?​

Answer 1

Step-by-step explanation:

Let the number be x.

(-9/7+2/3) + x = 16/5

LCM of 7 and 3 is 21.

(-27 + 14 + 21x) / 21 = 16/5

Cross multiplication

5(-27 + 14 + 21x) = 16 × 21

-135 + 70 + 105x = 336

-65 + 105x = 336

105x = 336 + 65

105x = 401

x = 401/105
