Detailed Explanation (Question 10):
To convert ( \frac{325}{790} ) to a decimal and round it to the nearest hundredths place, follow these steps:
- Perform Division:
Divide the numerator (325) by the denominator (790). Using a calculator or long division:
[
\frac{325}{790} = 0.411392405
] - Identify the Hundredths Place:
In the decimal 0.411392405:
- The tenths place is 4 (first digit after the decimal).
- The hundredths place is 1 (second digit after the decimal).
- The thousandths place is 1 (third digit after the decimal).
- Round to the Nearest Hundredths:
To round to the hundredths place, look at the thousandths place. If the thousandths digit is 5 or greater, round up. If it is less than 5, keep the hundredths digit unchanged.
- In this case, the thousandths digit is 1 (less than 5). Thus, the hundredths place remains 1.
- Final Answer:
After rounding, ( \frac{325}{790} ) becomes 0.41.
