Answer 2

Calculation of the Ratio of Pen Cost to Pencil Cost

To calculate the ratio of the cost of a pen to the cost of a pencil, we need to know the specific prices of both items. The given information states that the pen is 1.5 times more expensive than the pencil. Let's assume the cost of the pencil is x units of currency.

Based on the given information, the cost of the pen would be 1.5 times the cost of the pencil, which is 1.5x units of currency.

Therefore, the ratio of the cost of the pen to the cost of the pencil is 1.5x/x, which simplifies to 1.5.

Similarly, the ratio of the cost of the pencil to the cost of the pen would be the reciprocal of the previous ratio, which is 1/1.5 or approximately 0.67.

So, the ratio of the cost of the pen to the cost of the pencil is 1.5, and the ratio of the cost of the pencil to the cost of the pen is approximately 0.67.

Please note that the actual prices of the pen and pencil were not provided, so the above calculations are based on the given information and assumptions.
