Answer 2

To solve this arithmetic expression, you need to find a common denominator for all the fractions and then add them together. The common denominator in this case is 156, which is the least common multiple of 13, 26, and 12.

Let's rewrite the fractions with the common denominator:

(2 / 13) + (5 / 26) + (5 / 12)

= (2 * 12 / 13 * 12) + (5 * 6 / 26 * 6) + (5 * 13 / 12 * 13)

= (24 / 156) + (30 / 156) + (65 / 156)

Now, all the fractions have the same denominator, so we can simply add the numerators:

= (24 + 30 + 65) / 156

= 119 / 156

This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 13:

= (119 ÷ 13) / (156 ÷ 13)

= 9 / 12

Now, we can further simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3:

= (9 ÷ 3) / (12 ÷ 3)

= 3 / 4

So, the final result is 3/4.
