To find a way for Philip to sort his acorns so that each group has an equal number of acorns with tops and without tops, we should first look at the total counts.
Philip has:
- 66 acorns with tops
- 26 acorns without tops
This gives us a total of 92 acorns.
To sort them into equal groups, we need to factor both the number of acorns with tops (66) and the number without tops (26) to find a common divisor.
Let's check the number of groups he can form:
For 66 acorns (with tops): The factors are: 1, 2, 3, 6, 11, 22, 33, 66
For 26 acorns (without tops): The factors are: 1, 2, 13, 26
The common factors of 66 and 26 include 1 and 2. Hence, the maximum number of groups Philip can create, where he has equal parts of both types in his groups, is with the common factor 2.
If he sorts them into 2 groups:
- Each group will have \( \frac{66}{2} = 33 \) acorns with tops
- Each group will have \( \frac{26}{2} = 13 \) acorns without tops
Thus, he can represent how he should sort the acorns as: \[ 2(33 + 13) \]
Among the provided options, the correct answer is: 2(33 + 13).
