Question

What is the result of $2 minus 11 over 39 plus 5 over 26$

hint Hint:

Take LCM and add the fractions with the same denominator.

The correct answer is: 149/78

To find $2 minus 11 over 39 plus 5 over 26$
Taking the LCM of 39 and 26, we have 78 as LCM.
So, $2 equals 2 over 1 equals fraction numerator 2 cross times 78 over denominator 1 cross times 78 end fraction equals 156 over 78$ and
$11 over 39 equals fraction numerator 11 cross times 2 over denominator 39 cross times 2 end fraction equals 22 over 78$ and
$5 over 26 equals fraction numerator 5 cross times 3 over denominator 26 cross times 3 end fraction equals 15 over 78$
So, $2 minus 11 over 39 plus 5 over 26 equals 156 over 78 minus 22 over 78 plus 15 over 78$
