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.
3.180 pounds
B.
3.200 pounds
C.
3.000 pounds
D.
3.190 pounds

Answer 1

To round 3.185 to the nearest hundredth, we look at the digit in the thousandths place, which is 5. Since 5 is equal to or greater than 5, we round the hundredths place (8) up by 1.

Thus:

• The hundredths place (8) becomes 9.
• The digits after the hundredths place are dropped.

So, 3.185 rounded to the nearest hundredth is 3.190.

The correct answer is D. 3.190 pounds.
