How do you write 2/100,000 as a decimal? !

2/100000 as a decimal would be .000002. All you have to do is count the zeros in 100000, and then put a two after the zeros. If the number was 16 instead of two, and it had two didgets, you would count the zeros and subtract equal to the number of didgets minus one. Therefore 16/100000 would be .00016

X= -5because this is a single step equation so you would just have to divide -16 both sides for x to equal your solution
