Janie dug up 3.185 pounds of dirt from around a rose bush in her backyard. She measured the dirt and recorded the rounded amount to the nearest hundredth.

Question

Which amount of dirt was recorded?
A.
3.200 pounds
B.
3.180 pounds
C.
3.000 pounds
D.
3.190 pounds

Answer 1

To round 3.185 pounds to the nearest hundredth, we look at the third decimal place (the thousandths place), which is 5. According to rounding rules, if the digit in the thousandths place is 5 or greater, we round up the second decimal place (the hundredths place) by 1.

Here, the second decimal place is 8, and because the third decimal place is 5, we round up:

• 8 + 1 = 9

Thus, 3.185 rounded to the nearest hundredth is 3.190.

Therefore, the correct answer is: D. 3.190 pounds
