Jeremy has 18 marbles. he lost 6. what is the fraction of lost. and what is the fraction of marbles left. show work.

Lets divide the problem is parts, one for the fraction lost, and other for the fraction left.
For the fraction lost, it is said that from 18 marbles, 6 are lost, if we write that as a fraction that is:
6 out of 18 = 6/18
now simplifying it
6/18 = 3/9 = 1/3
so 1/3, one third, or one out of three, is lost.
The fraction left is the subtraction of the initial 18 marbles minus 6, that is 12:
12 out of 18 = 12/18 = 6/9 = 2/3
then the fraction of marbles left is 2/3

+1,000)=g7e=mc2-g=7 because if you know algebra you should know g=7 to get your answer
