Answer 3

Number of Pencils in Three Boxes

If there are 20 pencils in 5 identical boxes, we can calculate the number of pencils in three such boxes by finding the ratio of pencils to boxes and multiplying it by the number of boxes.

Let's calculate it step by step:

1. Determine the ratio of pencils to boxes: 20 pencils / 5 boxes = 4 pencils per box.

2. Multiply the ratio by the number of boxes: 4 pencils per box * 3 boxes = 12 pencils.

Therefore, there would be 12 pencils in three identical boxes.

Number of Boxes for 54 Pencils

If there are 72 pencils in 8 identical boxes, we can calculate the number of boxes needed for 54 pencils by finding the ratio of pencils to boxes and dividing the total number of pencils by that ratio.

Let's calculate it step by step:

1. Determine the ratio of pencils to boxes: 72 pencils / 8 boxes = 9 pencils per box.

2. Divide the total number of pencils by the ratio: 54 pencils / 9 pencils per box = 6 boxes.

Therefore, you would need 6 boxes for 54 pencils. I hope this helps! Let me know if you have any further questions.
