Question

On Thursday, 15,218 students were at a museum. On Friday, 4,379 students were at the museum. What is the difference between the numbers of students at the museum on Thursday and Friday? (1 point)

Answer 1

To find the difference between the number of students at the museum on Thursday and Friday, you subtract the number of students on Friday from the number of students on Thursday.

Number of students on Thursday: 15,218
Number of students on Friday: 4,379

Difference = 15,218 - 4,379

Now, we perform the subtraction:

1. Starting from the rightmost digit:
- 8 - 9 cannot be done, so we borrow 1 from the next column (which turns the 1 in the tens column into 0, and the 2 into 12).
- 12 - 9 = 3

2. Moving to the tens column:
- 0 - 7 cannot be done, so we borrow 1 from the next column (turning the 2 into 1, and the 0 into 10).
- 10 - 7 = 3

3. Moving to the hundreds column:
- 1 - 3 cannot be done, so we borrow 1 from the next column (turning the 5 into 4, and the 1 into 11).
- 11 - 3 = 8

4. Moving to the thousands column:
- 4 - 4 = 0

5. Moving to the ten-thousands column:
- 1 - 0 = 1

Putting it all together, we have:

15,218 - 4,379 = 10,839

Thus, the difference between the numbers of students at the museum on Thursday and Friday is **10,839**.
