A chicken farmer collected 412 eggs in March and 596 in April. How many more eggs were collected in April? Round your numbers to the nearest 10.
- A.
80 eggs

Lindsey wants to estimate how many comic books she and her friends have. She has 2,169, Les has 6,131 and Neil has 2,702. Round to the nearest tens. They have a total of _____________ comic books.
Correct Answer
11,000
11000
11 000Explanation
Lindsey has 2,169 comic books, Les has 6,131 comic books, and Neil has 2,702 comic books. To estimate the total number of comic books, we need to round each individual number to the nearest tens. Rounding 2,169 to the nearest tens gives us 2,170, rounding 6,131 gives us 6,130, and rounding 2,702 gives us 2,700. Adding these rounded numbers together, we get a total of 2,170 + 6,130 + 2,700 = 11,000 comic books.Rate this question:

634 - 541 =
Correct Answer
93Explanation
The given question requires subtracting 541 from 634. When subtracting, we start from the rightmost digit and subtract each corresponding digit. In this case, 4 minus 1 equals 3, 3 minus 4 is -1, and 6 minus 5 is 1. Since we have a negative result in the middle, we can borrow 1 from the leftmost digit, resulting in 5 minus 4 equals 1. Therefore, the correct answer is 93.Rate this question:
