Oh, dude, rounding 21 to the nearest hundred? That's like asking me to find a unicorn in a haystack. But hey, technically speaking, when you round 21 to the nearest hundred, it stays as 21. It's like trying to make a penny into a dollar - just not gonna happen.
When rounding 20.50 to the nearest whole number, you look at the digit immediately to the right of the decimal point, which is 5. Since 5 is equal to or greater than 5, you round up. Therefore, 20.50 rounded to the nearest whole number is 21.
21 rounded to the nearest hundred is zero. -- The even hundred above 21 is 100. -- The even hundred below 21 is zero. -- 21 is closer to the lower one than it is to the higher one.
