Answer:
450
Explanation:
50 is the closest ten to 52.
Remember:
4 and under is rounded to the ten that's lesser than the other.
5 and up is rounded to the ten that's more than the other.
Example: Your number is 74. Because it's a 4 and under number, it would be rounded to 70.
Example 2: Your number is 47. Because it's a 5 and up number, it would be rounded to 50.
Hope this helps!
