What is 0.8637 rounded to the nearest hundredth?

0.86

The second digit to the right of the decimal point is in the hundredths place and the third number to the right of the decimal point is in the thousandths place. The number in the hundredths place increases by 1 when the number in the thousandths place is 5 or greater. The number in the hundredths place remains the same if the number in the thousandths place is less than 5. Since the number in the thousandths place is less than 5, the number 0.8637 should be rounded down to 0.860.

A travel soccer team has 39 players. Each charter van fits 4 players. How many vans does the team need to fit all of their players?

10

To find the total number of vans, we divide 39 by 4, which gives us a quotient of 9, with a remainder of 3. Since we cannot leave anyone on the team behind, we must have another van for the remaining 3 people. This gives us 9 + 1 = 10 total vans.

Xiaoming is making cookies. Each batch of cookies uses 3 eggs. If Xiaoming has 20 eggs, and assuming he has enough of the other ingredients to make the cookies, what is the greatest number of batches that he can make?

6

If Xiaoming has 20 eggs, and each batch of cookies uses 3 eggs, the number of batches can be found by dividing 20 by 3. This does not divide evenly, so the number should be rounded down to 6 because Xiaoming does not have enough eggs to make 7 (3 × 3 eggs) batches (7 × 3 = 21).
3 is incorrect because 3 batches would use only 9 eggs . This means that Xiaoming would have 11 eggs left, which is enough to make more batches. 7 is incorrect because 7 batches would use 21 eggs (3 × 7 = 21), but Xiaoming has only 20 eggs. 17 is incorrect because 17 batches would use 51 eggs (17 × 3 = 51), but Xiaoming has only 20 eggs.

A conference planner has put together 280 binders for attendees and another 31 binders for presenters. How many total binders did the planner put together for attendees and presenters?

311

The total number of binders the planner put together for attendees and presenters is 280 + 31 = 311. Adding the ones place (0 + 1) results in the digit 1, adding the tens place (8 + 3) results in the number 11, which should be recorded as a 1 in the tens place and a 1 carried to the hundreds place, then adding the hundreds place (2 + 1) results in the digit 3.
211 results from not carrying a 1 to the hundreds place after adding the tens place. 249 is the result of subtracting the presenter binders from the attendee binders. However, the total number of binders will be found through addition, not subtraction. 590 is incorrect. This answer results from incorrectly adding the numbers.
