Question

What should be added to
-7/9 to get 2.

Answer 1

Answer:

25/9 should be added to -7/9 to get 2

Step-by-step explanation:

We need to find what should be added to  -7/9 to get 2.

Let the number to be added be x

According to question,

(-7/9) + x = 2

[(-7) + 9x] / 9 = 2

-7 + 9x = 2 × 9

-7 + 9x = 18

9x = 18 + 7

9x = 25

∴ x = 25/9

So, 25/9 should be added to -7/9 to get 2.

Answer 2

Given :

A fraction $\frac{-7}{9}$

To Find :

What should be added to  -7/9 to get 2.

Solution :

Let 'x' be the number that should be added to $\frac{-7}{9}$ to get 2.

As per question,

    $\frac{-7}{9}$  +  x     =   2

In order to find the value of x, we'll send $\frac{-7}{9}$ to the right side of equal sign. When $\frac{-7}{9}$  goes to the right hand side of the equal sign it becomes + $\frac{7}{9}$

⇒           x     =   2 + $\frac{7}{9}$

⇒           x     =  $\frac{18 + 7}{9}$

⇒           x     =  $\frac{25}{9}$

Therefore, $\frac{25}{9}$ must be added to $\frac{-7}{9}$ to get 2.
