If I measure my big screen TV and get 500.24 centimeters, which numeral is estimated? How many millimeters is it?
The last number is an estimate. Convert that many cm to mm.
5002.4
I don't think that is the question.
The 4 is the estimated number so it is .04 cm which converts to 0.4 mm.
But your answer is correct if you interpret the question assize in mm of the TV screen.
To determine which numeral is estimated in your measurement of 500.24 centimeters, you need to consider the smallest unit that you have measured. In this case, the smallest unit is the hundredth of a centimeter, which is the decimal part of 0.24. Since the hundredth place is the smallest unit measured, the numeral in the hundredth place (i.e., the digit 2) is estimated.
To convert centimeters to millimeters, you need to understand that there are 10 millimeters in 1 centimeter. So, to calculate the measurement in millimeters, you would multiply the measurement in centimeters by 10.
In this case, multiply 500.24 centimeters by 10:
500.24 centimeters * 10 = 5002.4 millimeters
Therefore, your measurement of 500.24 centimeters is estimated in the hundredth place, and it is equivalent to 5002.4 millimeters when converted.
