Final answer:
To distribute Rita's 10 pens evenly in 2 boxes, divide the pens between the boxes, resulting in each box containing 5 pens. This simple arithmetic problem falls under the subject of mathematics in a middle school level.
Step-by-step explanation:
Rita has 10 pens, and she wants to put them into 2 boxes, with each box having the same number of pens. The question involves basic arithmetic and division, making it a mathematics problem suitable for a middle school student. To evenly distribute Rita's pens in 2 boxes, we simply need to divide the total number of pens by the number of boxes, which is 10 pens divided by 2 boxes.
The calculation is as follows:
- Divide the total number of pens by the number of boxes: 10 ÷ 2 = 5.
- Therefore, each box will contain 5 pens.
