Round off 4252 to one significant number

4252 rounded is 4000.

Explanation:
When it says "significant number", we assume to round to the nearest thousand. To do this, we look at the hundredths place. If the number in the hundredths place is 1-4, we keep the 4000. If the number is from 1-5, we round up to 5000. Since the hundredths place is 2, we round down to 4000.

4000, One significant number means to round it off to 1 digit. Here  4252 is near to 4000 rather than 5000. Considering 4784 (a random number), it is nearer to 5000 rather than. In simple terms it means to round off to the nearest whole number.
