Hope this helps :)
Here are 18 brown haired students out of 40 students 18/40=0.45
0.45
2/8, 3/12, 4/16, 5/20, 6/24, 7/28, 8/32, 9/36, 10/40, 11/44, 12/48, etc.
For a solution of 'all real numbers' to occur, you must end up with a statement that is true no matter what
example
simplifying results in x=x or 8=8 or 0=0 or something liek that
an example equation would be 2(x+1)=2x+2, simplifies to x=x or 2=2 or 0=0
no solution is when you get a false statement from simplifying
example, 3=4 or -1=0
an example equation could be 2(x+1)=2x+3, it simplifies to 2=3 which is false
