Variant 1 answer: 7 cookies

Some cookies were packed equally, 1414 to a bag, making 22 bags. If these same cookies are repacked equally into 44 bags, how many cookies can be put in each bag?

Show solution

Understand

Cookies were packed 14 to a bag into 2 bags. The same cookies are then repacked equally into 4 bags. I need to find how many go in each of the new bags.

Givens
  • Each original bag holds 14 cookies.
  • There are 2 original bags.
  • All the cookies are repacked equally into 4 bags.
Unknowns
  • The number of cookies in each of the 4 new bags.
Constraints
  • The cookies are split equally with none left over.
  • The total number stays the same when repacked.

#7 Identify Subproblems 3.OA.A.3
There are 2 bags with 14 cookies each, so multiply to find how many cookies there are altogether.
14×2=2814 \times 2 = 28
Equal groups are counted by multiplying the group size by the number of groups.
#8 Analyze the Units 3.OA.A.3
The same 28 cookies are repacked equally into 4 bags, so divide the total by the number of new bags.
28÷4=728 \div 4 = 7
Sharing a total equally into a known number of groups is exactly what division finds.
Answer: 7 cookies

Review

Check: 7 cookies per bag times 4 bags equals 28, the same total we started with.

Look for a pattern (tool 5): multiplying the number of bags by 2 divides the count per bag by 2: 14 becomes 7 without computing the total at all.
