Answer 1

You have to add 2 1/2+ 2 3/5= 5 1/10 So 1/10 

Answer 2

Yolanda will have 1/10 of a pound left over. You want to get both of the denominators the same (the bottom number in a fraction) Luckily they both can go into 10. So we multiply each by whatever number is needed to get them to 10 and do the same to the top number. for 1/2, we multiply the top and bottom by 5 because 5*2 equals 10. We now have 5/10. We then multiply 3/5 by 2 on both sides because 5*2 equals 10. We now have 6/10. We add 5/10 and 6/10 to get 11/10. If we add the whole numbers to that, we get 4 11/10 which will simplify down to 5 1/10. We now have 1/10 left over
