What is 15.992 to the nearest tenth?

Answer 1

When rounding to the nearest tenth (or other fraction), you always look at the next number. Here, in 15.992 the next number is 9 (second place after decimal point), therefore it rounds up. As the next number (first place after decimal point) is also 9, this also rounds up, giving the result of 16.0.

(If the number to round would be for example 15.945, the result rounded to the nearest tenth would be 15.9)
