Answer:

Step-by-step explanation:
The fraction and percentage will be the number of black pens divided by the total number of pens.
We can find the total number of pens by adding all the pens in each color together.
2 + 4 + 3 + 1 = 10
The total number of pens is 10. The number of black pens is 4.
The fraction will be 4/10, or 2/5.
The percentage will be 40%.
