How would I round the square root of six (2.4494) properly would it be
a) 2.5
Or
b) 2.4
Because although the hundredth is a four the thousandth is a nine?
Thanks in advance

Rounded to two digits 2.4459 is 2.4, since 0.4459 is closer to 0.4 than to 0.5. Rounded to three digits it would be 2.45, as .0459 is closer to .05 than 0.04.

Thanks a lot!
