Answer:
2
Explanation:
Any multiple of 5 ends in 0 or 5.
To find the remainder when a number is divided by 5, we can find the highest number less than or equal to the given number that ends in 0 or 5, then subtract that number from the given number.
In this case, the highest number that ends in a 0 or 5 that is less than or equal to the given number is 285.
When we subtract that from the given number, 287, we get:
287 - 285 = 2
