What is the product of 2.5 and 0.4?

• A. A) 1.0
• B. B) 0.8
• C. C) 1.2
• D. D) 0.9

Answer: (A)

To find the product of 2.5 and 0.4, you multiply the two numbers together. Begin by rewriting the decimal numbers as fractions for clarity: 2.5 can be written as \( \frac{25}{10} \), and 0.4 can be written as \( \frac{4}{10} \). Thus, the multiplication can be represented as: \[ \frac{25}{10} \times \frac{4}{10} = \frac{100}{100} = 1 \] Now, if we multiply 2.5 and 0.4 directly using traditional multiplication: - First multiply 25 and 4 to get 100. - Then, since there are one decimal place in 2.5 and one decimal place in 0.4, the result must be divided by \(10 \times 10 = 100\). So, 100 divided by 100 gives 1. Therefore, the product of 2.5 and 0.4 is indeed 1. This confirms that the correct answer reflects the accurate calculation of the multiplication.

To find the product of 2.5 and 0.4, you multiply the two numbers together.

Begin by rewriting the decimal numbers as fractions for clarity:

2.5 can be written as ( \frac{25}{10} ), and 0.4 can be written as ( \frac{4}{10} ). Thus, the multiplication can be represented as:

[

\frac{25}{10} \times \frac{4}{10} = \frac{100}{100} = 1

]

Now, if we multiply 2.5 and 0.4 directly using traditional multiplication:

• First multiply 25 and 4 to get 100.

• Then, since there are one decimal place in 2.5 and one decimal place in 0.4, the result must be divided by (10 \times 10 = 100).

So, 100 divided by 100 gives 1. Therefore, the product of 2.5 and 0.4 is indeed 1. This confirms that the correct answer reflects the accurate calculation of the multiplication.
