Hi all, The older my son gets, the more stupid I feel when trying to help him with math. He is in 7th grade and here is the "Problem of the Week". Maxine has a piece of ribbon that measures 10 feet, 1 1/2 inches. She cuts it into 5 pieces. The second piece is twice as long as the first. The third piece is 5 inches less than twice the length of the second piece. The fourth piece is half the length of the second piece The fifth piece is equal to the sum of the lengths of the first and second piece.
How long is each piece?

"Show ALL of your work AND explain your reasoning.

This one has got me scratching my head all night and all day today. Can someone please give me a clue where I should even start with this one? There must be a common denominator, but I can't seem to find it. Thanks in advance!
