4.2

Explanation:

When rounding a number to the nearest value, we look at what the next value is. If the next value is greater than or equal to 5, then we round the value up one place.

In your question, the next value (the hundredth) is 8, so the tenth value (1) would be rounded up. All the numbers after the tenth value would be 0 (all the numbers after the number that has been rounded are 0).

If the hundredth value had been less than 5 (such as 4.12), then the tenth value would have stayed the same. 4.12 rounded to the nearest tenth would be 4.1, but since your number is 4.186666667, it would be rounded to 4.2.

Explanation:

#4.186666667#
when rounding off to the nearest tenth, we look at the number hundredth place, which is #8# in this case. Since #8# is greater than #4#, the number at the tenth place, which is #1#, will be rounded up to #2#.
