Paraphin [41]
Salutations!

What is 529.062 round to the nearest tenth?

To round the number to the nearest tenth, you need to know whether the number is greater than 5 or lesser than 5. If its greater than 5, you need to round up. If its lesser than 5, you need to know round down.

In the number, 529.062, the number next to the tenth place is 6. 6 is greater than 5, therefore, you need to add +1 to the tenth place making it 1.

529.062 round to the nearest tenth ≈ 529.1.

Hope I helped (:

Have a great day!
