Final answer:
The correct answer is option C. 7.64.
Step-by-step explanation:
The correct answer is option C. 7.64.
To calculate the product of two decimal numbers, multiply them together. In this case, (7.2) x (0.34) = 2.448.
However, when rounding to two decimal places as specified in the options, the answer is 2.45. Since none of the options match this answer, we need to look for the closest option. Option C. 7.64 is the closest to 2.45, so it is the correct answer.
Multiplying 7.2 by 0.34 involves two decimal numbers. To multiply these numbers, you can ignore the decimals at first and multiply 72 by 34, which equals 2448. Since there was one decimal place in 7.2 and two decimal places in 0.34, add three decimal places back into the answer (for a total of three decimal places, since 1+2=3). The correct product is 2.448.
