I would add the 10 2/3 to the 1 7/8. To add the fractions, I need to find the least common denominator. It would be 24. so it'd be 10 16/24+ 1 21/24= 11 37/24. To make the 11 37/24 a proper mixed fraction, I see that the numerator is bigger than the denominator and that 24 can go into 37 one time. So I would add 1 to the 11 to get 12. Then I put the remainder over 24 which would be 13/24. I think your final answer would be 12 13/24 if I did this correctly. So she would have had 12 13/24 inches of hair cut off.
