2.50 X 0.25 Simplify the expression above. Which of the following is correct?

Rationale

0.625 is the correct solution to the expression 2.50 X 0.25.

When multiplying decimal numbers, you perform the multiplication as if they were whole numbers and then count the number of digits after the decimal point in the original problem. In this case, there are two digits after the decimal in 2.50 and two digits after the decimal in 0.25, which means the answer must have four digits after the decimal.

A (6.25) YOUR ANSWER

This solution would be the result if the multiplication was performed without considering the decimal places. However, it does not account for the two decimal places in each of the original numbers, so it's incorrect.

B (0.0625) YOUR ANSWER

This solution seems to overcompensate for the decimal places in the original numbers. Instead of having four digits after the decimal, it has five, which is one too many.

C (6.025) YOUR ANSWER

This solution doesn't match the multiplication of the original numbers (2.50 and 0.25). It seems to be a misinterpretation of the decimal placement.

D (0.625) CORRECT

This is the correct solution. Multiplying 2.50 and 0.25 as if they were whole numbers gives 625. Since the original problem has a combined total of four decimal places (two in each number), the answer must also have four digits: 0.625.

Conclusion

When multiplying decimal numbers, the multiplication should be done as if they are whole numbers, and then the total number of decimal places in the original problem should be counted and applied to the answer. The solution to the expression 2.50 X 0.25, when taking into account the correct number of decimal places, is 0.625.

2.50 X 0.25 Simplify the expression above. Which of the following is correct?

0.625 is the correct solution to the expression 2.50 X 0.25.
