To make this simpler, let's first convert these into improper (or "bobblehead" fractions.) This will give us 18/5 and 5/2.
Now we should try to find a common denominator by finding the smallest common multiple of 5 and 2. In this case, the answer is 10, so we want to convert both denominators to ten. We can do this by multiplying top and bottom by whatever factor will make the bottom ten.
This will give us the numbers 36/10 and 25/10.
Now we can simply add the numerators and put them over ten! This will give us 51/10, which is our answer!
