Step-by-step explanation:

We have to find the Least Common Denominator.

Sooo..

$\frac{3}{4} and \frac{2}{5}$

The LCD is 20

because you can multiply 4*5 = 20 and 5*4= 20

Now turn the mixed numbers into improper fractions.

$\frac{11}{4} and \frac{17}{5}$

To get the same denominator do this.

$(\frac{5}{5}) \frac{11}{4} + (\frac{4}{4})\frac{17}{5} \\\\\frac{55}{20} + \frac{68}{20} \\\\\frac{123}{20} \\\\6\frac{3}{20}$

Hope this helps ya! Keep smiling!
