Isabel spent 3/12 of eachuear on summer break from school what is the total amount of time that label spend in school in 5years

5+4

To determine the number of pens with black ink, you need to calculate 3/4 of the total number of pens in the package.

Here's the step-by-step process:
1. Start with the total number of pens in the package, which is 20.
2. Multiply the total number of pens by the fraction representing the proportion of pens with black ink, which is 3/4.
- 20 * (3/4) = 15
3. Hence, Jared has 15 pens with black ink.
