Answer:
Step-by-step explanation:
15 bags for $20 can be represented with 15/20
so x bags for $4 can be represented with x/4
now if you proportion it out (ricochet), 4x15 is 60, 60 divided by 20 is 3, so you can buy 3 bags of potatoes with $4.
OR
you could do 15/20 is 0.75
0.75 times 4 is 3, so $4 can buy you 3 bags.
