For this problem, we need to find the GTD or greatest common denominator.
So we see we have 1/5 and 3/4.
To get the GTD lets multiply 5 and 4 which gets us 20.
Now we have to multiply 1 by 4 which gets us 4. And we also need to multiply 3 by 5 which gets us 15.
Now we set up the fractions.
4/20 and 15/20
Now we can easily add the two fractions!
19/20
