Answer:
A: 19.3 and 19.25
Step-by-step explanation:
When rounding decimals if the number in the decimal place to the right is higher than 5 you round up. If not keep keep the same.
The rounding off 19.254 to the nearest tenth and the nearest hundredth will be 19.3 and 19.25 respectively.
What is rounding off ?
Rounding off means a number is made into simpler form by keeping its value fixed but closer to the next number.
To round off the number to the nearest tenth we need to look at the hundredths place digit. If the digit is 1, 2, 3, 4 then we don't have to do anything, if the digit is 5, 6, 7, 8, 9 we must round up.
here, The number 19.254 at tenth place is 5 so round up the hundredths place digit, hence the rounded off to the nearest tenth will be 19.3.
and also,
To round off the number to the nearest hundredth we need to look at the thousandth place digit. If the digit is 1, 2, 3, 4 then we don't have to do anything, if the digit is 5, 6, 7, 8, 9 we must round up.
here, The number 19.254 at hundredth place is 4 so round up the thousandth place digit, hence the rounded off to the nearest hundredth will be 19.25.
Therefore, the rounding off 19.254 to the nearest tenth and the nearest hundredth will be 19.3 and 19.25 respectively.
