Answer:
53,000
Explanation:
One way you can do this is to add half the place value you're rounding to:
52785 +(1000/2) = 52785 +500 = 53284
Now, set all digits to the right of that place to zero:
53000
The value 52785 rounded to thousands is 53000.

Additional comment
The usual instruction is to look at the digit in the place to the right of the one you're rounding to. The digit to the right of the 1000s digit is the 100s digit. That digit is 7.
When the digit is more than 4, then you need to increase the number by 1 in the place you're rounding to. That means the 2 in the thousands place needs to increase to 3 to make the number 53,000 after rounding. All digits to the right of the one you're rounding to are set to zero.
