NO.

It is .01754

Move 2 decimnal places to the right, you get 1.754%...

Now what is that rounded to the nearest percent?

Answer 16

1.75

Answer 17

no wait 1.8

Answer 18

No, you want to round off to the nearest tenth...that means, I only want to see one digit after the decimal point

So to round off, you look at the 2nd digit after the decimal point. If it is a 5 or greater, thaen you round up.

In this case, the 2nd digit is a 5, so 1.7 goes up to 1.8%.

Answer 19

Correct, 1.8%.

Answer 20

Correct, 1.8%.
