Answer :

So, to solve the questions on your paper, you need to first have all of the bottom numbers on the fractions similar numbers.  So if you have the numbers 1/4 and 4/8, you need to get them to both be the same number.  Therefore, 1/4 should become 2/8, because you doubled the bottom number (you also then need to do the same to the top number).  You don't need to change 4/8, because it's bottom number is already 8.  Then, you can take 4/8 and 1/8 and add them.  To add them, you just add the top numbers.  The top numbers make 5, so then you add the denominator, and make the number 5/8.  Since you can't simplify 5/8, just keep it.  But if it was 4/8, you could simplify it to 1/2.  You can do all of this same to all of the numbers on your paper.  :D  If you are subtracting, subtract only the top numbers, but if you need to multiply or divide, multiply/divide both numerator AND denominator.  :D I hope I helped!  If I didn't, please tell me, or just delete my answer. :D
