I have a math problem: 3 People share income and loss in a 3:2:1 ratio. Does that mean 30%, 20%, and 10% or what? If someone can tell me what this means then I can finish the rest of the problem. Thanks

I understand that when we look at distant stars in the night sky we are looking at light that has taken many years to reach us. But does that light and indeed all light have a power source and if so what is it?

Well, after looking through my Algebra I homework, I come to this problem:

A number plus five, divided by two, added to the quotient of that same number minus one, divided also by two, has a sum of that number minus one, divided by three.

Simply put, [(x+5)/2]+[(x-1)/2] equals [(x-1)/3].

These are all fractions, and when I solved it, I got a soultion of 3.5, which doesn't seem right. I multiplied the entire expression by the LCD, six, and divided the resulting binomials by the monomials in the denominator. It still doesn't seem right.

Did I make a mistake? How do I solve this?
