Show hints
Hint 1 of 3
First add up how many apples are still left in all three bags.
Still stuck? Show hint 2 →
Hint 2 of 3
Maria started with 19, so the apples she took are the 19 minus the ones still left.
Still stuck? Show hint 3 →
Hint 3 of 3
She took the same number from each bag, so share the taken apples equally among 3 bags.
Show solution
Approach: find how many were taken in all, then share among 3 bags
- Count the apples still in the bags: 3 and 4 and 6 make 13.
- Maria began with 19, so the apples she took away are 19 take away 13, which is 6.
- She took the same from each of the 3 bags, so share 6 into 3 equal groups: 2 from each bag, option B.
