Answer:
124.6135 grams to the nearest kilogram would be none if you want to round how you are supposed to, or one if round to the next number up.
Explanation:
What is 124.6135 grams compared to kilograms? Well, it's simple. A single kilogram has kilo in it. Kilo is a prefix meaning thousand, so therefor, a kilo gram is a thousand grams. since you have 124.6135 grams if you divide that by a thousand, you get 0.1246135. And using the rounding rule five or more, raise the score, four or less, let it rest; 1 is less than four so it would be zero.
