Final answer:
The number 200 rounded to 1 decimal place is 200.0.
Step-by-step explanation:
The number 200 rounded to 1 decimal place is 200.0. When rounding to 1 decimal place, we look at the digit in the tenths place (the first digit after the decimal point). If this digit is 5 or greater, we round up by increasing the digit in the ones place by 1. In this case, 0 is less than 5, so we leave the digit in the ones place as it is and the rounded number remains 200.0.Rounding to 1 decimal place implies specifying a single digit after the decimal point. In this instance, 200.0 emphasizes the precision to the tenths place, with the trailing zero signifying the absence of further decimal digits.
