1. When rounding to the tenths place, which of the following numbers rounds to 87.5
Answer: C
87.459 rounds to 87.5 when rounded to the tenths place.
When rounding to the tenths place, the number 87.459 rounds to 87.5 because the digit in the hundredths place (5) indicates that we round up.
A) 88
88 does not round to 87.5; rather, it rounds to 88.0 when considering the tenths place. Since it is higher than 87.5, it cannot be a correct answer.
B) 87.56
87.56 rounds to 87.6 when rounded to the tenths place because the digit in the hundredths place (6) causes an upward rounding. Therefore, this option is also incorrect.
C) 87.459
87.459 rounds to 87.5 when rounded to the tenths place, as the digit in the hundredths place (5) triggers the rounding up. This makes it the correct answer.
D) 87.05
87.05 rounds to 87.1 when rounding to the tenths place because the digit in the hundredths place (0) does not cause any upward rounding. Thus, this option is incorrect.
Conclusion
The number 87.459 is the only option that correctly rounds to 87.5 when considering the tenths place, due to the rounding rules based on the hundredths digit. All other options either round to a different value or do not meet the criteria for rounding to 87.5.
