Answer :
To solve the problem 8.21 x 1.01 and reduce the answer to the nearest tenth, we need to follow these steps:
1. Perform the Multiplication:
Multiply 8.21 by 1.01.
[tex]\[
8.21 \times 1.01 = 8.2921
\][/tex]
2. Round to Nearest Tenth:
Look at the number in the hundredths place (the second digit to the right of the decimal).
In this case, the number is 2.
- If the number in the hundredths place is 5 or greater, round up.
- If the number in the hundredths place is less than 5, round down.
Since the hundredths place is 2 (which is less than 5), we round down.
[tex]\[
8.2921 \approx 8.3
\][/tex]
Therefore, the correct answer to 8.21 x 1.01, rounded to the nearest tenth, is:
[tex]\[
\boxed{8.3}
\][/tex]
This matches the multiple-choice option d. 8.3.
