Jeremy has 18 marbles. he lost 6. what is the fraction of lost. and what is the fraction of marbles left. please 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
the marbles lost are 6/18, or 2/6, or even 2/3. it's all the same. the fraction of marbles left are 12/18, or, 6/9, or 2/3. Again. the work is 6÷3=2 and 18÷3=3. so its 2/3. 12÷6=2 and 18÷6=3. so it's 2/3. they are the same thing. hope it helps.
