The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(1/5, 1/6) = 30
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(1/5×6/6)+(1/6×5/5)=?
Complete the multiplication and the equation becomes
630+530=?
The two fractions now have like denominators so you can add the numerators.
6+5/30=11/30
The fraction cannot be simplified, final answer 11/30
