0.2

0.18

0.19

0.186 rounded to the nearest tenth is 0.2. When rounding to the nearest tenth, we look at the digit in the hundredth place, which is 8 in this case. Since 8 is greater than or equal to 5, we round up the digit in the tenth place, which is 1, to the next higher number, which is 2. Therefore, the rounded number is 0.2.

Explanation

0.186 rounded to the nearest tenth is 0.2. When rounding to the nearest tenth, we look at the digit in the hundredth place, which is 8 in this case.
