Answer 3

Calculation of the Number of Pencils

To find out how many pencils are in 7 boxes, we can use a simple multiplication calculation. Given that there are 90 pencils in 15 boxes, we can calculate the number of pencils in 7 boxes by using the following formula:

Number of pencils in 7 boxes = (Number of pencils in 15 boxes / Number of boxes in 15 boxes) * Number of boxes in 7 boxes

Calculation

Using the given information: - Number of pencils in 15 boxes = 90 - Number of boxes in 15 boxes = 15 - Number of boxes in 7 boxes = 7

We can calculate the number of pencils in 7 boxes using the formula: Number of pencils in 7 boxes = (90 / 15) * 7

Result

By performing the calculation: Number of pencils in 7 boxes = (90 / 15) * 7 = 42

Therefore, there are 42 pencils in 7 such boxes.

So, the correct answer is 3. 42.
