Answer :
For this problem you would have to add. Why? Because if she had 6/8 left AFTER giving 1 and 1/8 to her neighbor, then she had MORE than 1 and 1/8. 1 and 1/8 plus 6/8= 1 & 7/8. Hope this helps, and please look at the pic I provided below to explain this. Thank you :)

You have to add the two numbers together. The 1 whole stays the same so we can leave that. 1/8+6/8=7/8. Therefore the answer is 1 7/8
