you just have to add and subtract
49 3/4 + 55 1/4 - 91 1/3=?
since they're in mixed fraction and doesn't have common denominator, then convert it into improper fraction and have LCD.
49 3/4 = 199/4
55 1/4 = 221/4
91 1/3 = 274/3
getting the LCD of the three, we have '12'
and you'll have 597/12 + 663/12 -1096 = 164/12 or 41/3 or 13 2/3 baskets
