Susan found a board to make a shelf. It was 4 3/5 feet long. She needed 4/9 of it for the shelf. How long was the shelf?






If you ask me Susan just needs to get a dam chainsaw!

That or buy a damn tape measure

those #'s dont make sense. if she needed 4/9ths of it, that would be .44

24.52" I think

4 7/45 ft left i think

Ok hopefully Im explaining this correctly, first I would convert the 4 3/5 all to one fraction so the 4 feet converted to fifths would be 20/5 then add that to 3/5 to have a total of 23/5 for the whole length of the board

Then I would multiply 23/5 x 4/9 which will give you 92/45 and then if you convert that into a mixed number it would be 2 2/45 feet for the total length of the shelf

OK this is how you do it take the 4 3/5 feet to inches which then becomes 55.2 inches Take 4/9 of the total length in inches then convert to ft. So about 2 1/2 ft
