Round to Nearest Non-Zero NumberDate: 11/13/2001 at 10:20:48 From: Rashad Subject: Rounding numbers How do you round this number to the nearest one non-zero number? 47,859,600 Is it 48 million? Date: 11/13/2001 at 12:28:55 From: Doctor Peterson Subject: Re: Rounding numbers Hi, Rashad. Since 48,000,000 has TWO non-zero numbers, not one, it can't be the answer. The largest digit in the given number is the ten-millions digit, so you want to round to the nearest ten million, rather than the nearest million. 47,859,600 rounds to 50,000,000, to one significant digit. Normally, we would say "round to one significant digit," but you probably have not seen that term. Your question means the same thing. - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/ |
