Answer key and explanations

C. 47.9
% Explanation Text The tenths place in 47.863 is 8. The hundredths place is 6. Since 6 is greater than or equal to 5, we round the tenths digit up from 8 to 9. Therefore, 47.863 rounded to the nearest tenth is 47.9.
-
A. 23
The tenths place is 4. Since 4 is less than 5, round down. 23.45 rounded to the nearest whole number is 23.
-
B. 5.68
The hundredths place is 7. The thousandths place is 8. Since 8 \(\geq\) 5, round up from 7 to 8. So 5.678 rounds to 5.68.
-
D. 12.5
The tenths place is 5. The hundredths place is 4. Since 4 < 5, keep 5. So 12.542 rounds to 12.5.
-
D. 3
3.47 is between 3 and 4, but closer to 3 because the tenths digit 4 is less than 5. It rounds down to 3.
-
A. 9.95
The hundredths place is 5. The thousandths place is 1. Since 1 < 5, keep the hundredths digit the same. So 9.951 rounds to 9.95.
-
C. 8.8 m
The tenths place is 7, hundredths is 6. Since 6 \(\geq\) 5, round up: 7 becomes 8. Maria uses 8.8 meters.
-
A. 34
The tenths digit is 1. Since 1 < 5, round down. 34.196 rounded to the nearest whole number is 34.
