Answer:
3400 grams.
Explanation:
We have been that Noah made 12 kg of trail mix for his family's hiking trip. His family ate 8600 g of the trail mix on the hiking trip.
Let us convert 12 kg into grams.
1 kg= 1000 grams
12 kg = 12*1000 grams =12000 grams.
Let u subtract 8600 from 12000 grams to find the amount of trail mix left.


Therefore, Noah had 3400 grams left of trail mix.
