6.429 round to the nearest tenth

6.4

Step-by-step explanation:

when rounding a number, the decimal points go from tenth, hundredth, and thousandth.

In this case, the number in the tenths place is 4.

Because the number next to 4, which is 2, is less than 5, it cannot raise the number of the number in the tenths place, so the 4 stays the same and the other two numbers after it are eliminated

This gives you 6.4 as your final answer.

I hope this helps you!
