Question

Round 4.465 as indicated by the question.
To two significant digits
a. 4.4
b. 4.6
c. 4.0
d. 4.5

Answer 1

Ok...do you have an idea of which one you think it is?

Answer 2

4.5. But can you please explain the concept? Is it as simple as I think it is?

Answer 3

If you're rounding it to 2 significant digits then you want to keep the two most significant digits...which in this case is X.X. In this case you're basically just rounding the ".46" to ".5".

Answer 4

Maybe it will help if we did the same thing for the value 4.432...rounded to 2 significant digits. That adjusted value of that would be "4.4" since the ".432" rounded to 1 digit is just ".4".

Answer 5

If it's still confusing you let me know and we can work through some more examples
