Answer:
2 and 3/7 pounds
Step-by-step explanation:
Convert the mixed number to an improper fraction
12 1/7 becomes 85/7
This represents 5 bags, so divide it by 5 to see what one bag should weigh...
(85/7)/5 becomes (85/7)/(5/1)
which becomes
(85/7)*(1/5) (division is the same as multiplying by the reciprocal)
85/35
17/7 (reduce the fraction by factoring out a 5 from top and bottom)
2 and 3/7 pounds
