16.437 rounded to the nearest whole number is 16 true or false

True.

Rounding to nearest whole number, you just have to look at the number right after the decimal point (dot).
since 4 is closer to 0, rounded number is 16.0, or, 16

This would be true.

That's because 4 come BEFORE 5 so, it stays at that number, and does not go to the next number.
