The final answer would be three and three-eighths. Here's how to solve it mentally.
You have to set their denominators [bottom numbers] equal. So, keep seven eights, since two ["half"] goes into eight, but you must make 2 and a half into 2 and four eights, because four is half of eight. Pretend for a minute that the four eights isn't there. So, 2 and seven eights. Then, add one from the four eights, so that it will now be 3., and so that the four eights is now three eights. So, 3 and three eights.
Sorry. I'm not very good at explaining, but I hope that helped. ^^"
