rational number should be added to minus 7 upon 18 to get 11

Answer 1

Heya!!

Here is your answer : -

Let the required no. be x.

To find,
what no. should be added to -7/18 to. get 11


Now framing a linear equation by utilising the given information.

$\frac{ - 7}{18} + x = 11$
Now this is a linear equation in one variable.

Now we will solve it for x using transposition.

$x = \frac{11}{1} + \frac{7}{18}$

Now taking LCM

$x = \frac{198 + 7}{18}$


$x = \frac{205}{18}$


Our required answer is x i.e 205/18
