Sagot :
9.725 rounded to the nearest tenth is 2.80.
All you have to do is add 5 to 2, assuming that 5 is 1. Then you get your answer.
So the basic idea of rounding is that your going to what 10 or 0, whichever is closer (5 goes to 10). In this case 9.725. 7 is in the 10th place so we look to the digit before it: 2, which is closer to 0. So we get 9.7. To show your work for that? Uh... not sure what there is to show. What I would do is underline the place you're rounding to, circle the digit behind it tell what its closer to, 10 or 0, and then show the rounded number... Hopefully that gave you the answer you needed
