Identify which one of these are exact numbers. (Can be more than 1)
a. 2.54 cm ( the number of centimeters in exactly 1 in)
b. 56.00 s ( a time measured by a stopwatch)
c. 4 choices ( the number of choices in this list)
d. 3 lbs ( the weight of an object measured on a scale )
a, b, c are correct. I don't think it can be d since not all scales are accurate and it only measures till the hundredths place and there could be a number after that.
