Answer:
By converting the fractions to the lowest common denominator you would have a total of 1 14/16 + 2 5/16 = 3 19/16 or 4 3/16 of peaches and strawberries. The total fruit bought, if converted would be 5 8/16. Subtract the total lbs. of strawberries and peaches bought(4 3/16) from the total lbs. of fruit bought(5 8/16) you would have a remainder of 1 5/16lbs. which would be the total lbs. of oranges bought.
