10. The fraction 325/790 converted to a decimal and rounded to the nearest hundredths place is _____

Romashka [77]

Answer: 325/790 rounded to the nearest hundredths place is 0.41

Step-by-step explanation:

if you divide 325/790 you get 0.411 and some other numbers. We only need to focus on these 3 numbers. 4 is the tenths place value and the first 1 is in the hundredths place value. Sense the second 1 (which is in the thousandths place value) is less than 5, we don't round the 1 in the hundredths place value up. Meaning your answer is 0.411.

Hopefully this makes sense.
