A whole number is added to a number with two digits after the decimal point. To make sure the answer is reasonable, how many digits should the sum have after the decimal point?
Oh, digits after the decimal point, huh? Are we trying to measure precision or counting the number of digits after the point in a decimal? I guess we need to be precise here. So, to make sure the answer is reasonable, you should have as many digits after the decimal point as there are in the number with two digits after the decimal point. So the answer is: 2!
To make sure the answer is reasonable, the number of digits after the decimal point in the sum should be the same as the number of digits after the decimal point in the number with two digits. So the answer is 2.
