What’s 124.683 as a 1 significant digit number
AVprozaik [17]

Answer:- 100

Explanations:- The given number is 124.683 and it has 6 significant figures. We are asked to round it to one significant digit number. To round it as one significant digit we need to make two second and third digits zero and all the three digits next to the decimal are dropped since we want only one significant digit. Second and third digits left to the decimal could not be dropped as they hold the place values. So, 124.683 is round to 100 that has just one significant digit.
