Convert mixed fraction into improper fraction.
Since we know that dividing a fraction with another fraction is same as multiplying the 1st fraction with the reciprocal of 2nd fraction.
After cancelling out 8 from numerator and denominator we will get,
Therefore, 17 bags each of weight 3/8 pounds can be made from
pounds of mix trail.
