Question

Round each number to the nearest tenth.

What is the best estimate for the answer to 47.82 + 74.31?

Answer 1

122.1 or 122
becuase the original answer is 122.13 and the 3 gets out becuase it rounds down and so does the 1

Answer 2

47.82 is rounded to 47.8 because the '2' in the hundredths column means you round down. The same goes for 74.31- it becomes 74.3 because the '1' in the hundredths column means you round down.

47.8+74.3= 122.1
