The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(11/4, 2/5) = 20

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.
(114×55)+(25×44)=?

The two fractions now have like denominators so you can add the numerators.

Then:
55+820=6320
