Sunbeam's group of close friends are going to fifth grade in September. All are going to Highway elementary school and their home rooms will be 12,14,or 16. All of her friends but 4 are going to room 12, all but 4 are going to room 14, and all but 4 are going to room 16. Not counting Sunbeam, how many people are in her group of close friends?
six , because if you mark number of friends with x you would get it like this : 3(x-4)=x
3x-12=x
3x-x=12
2x=12
X=12/2
X=6
and someone posted this question before you did
how do i mutipli fractoins
First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.
Just multiply the numerators and denominators.
2/3 * 3/6 = 6/18 = 1/3
2 *3 = 6 and 3 * 6 = 18
