Question

12.57 round to the nearest tenth

Answer 1

You get 12.6

After the decimal starts the the tenth place. In order to round to the tenth place, we need to know the hundredth place which is the 7. If the hundredth place is 5 or greater then we round up and if it's 4 or lower then we keep the tenth place the same number as it is before.

Since the hundredth place is greater than or equal to 5, we round up the tenth place to 6. If you have any questions then leave a comment. Good luck!

Answer 2

12.57 rounded to the nearest tenth is 12.6 because the 5 is the tenth place and you have to look at the number to the right of that which is 7. 5 and up rounds up, so the 5 becomes 6 and the 7 disappears.
