This problem doesn't lead to a whole number solution. Are you sure you copied it correctly? Maybe you meant the ratio is 4 to 3. In that case: red/blue = 4/3 blue/red = 3/4 blue = (3 * red) / 4 = (3 * 16) / 4 = 12 blue marbles

at least 39 blue marbles

Set up the problem as: y=number of yellow marbles & 4y=number of blue marbles. 40=y+4y or 40=5y or y=8. Therefore number of blue marbles is 4*8 = 32.

48 marbles

There are 26 total marbles. We will call x the number of blue marbles. So there are x+2 red marbles. If you add them together you get x + x + 2....and all that equals 26 (subtract 2 from each side and add the two x's together) 26 - 2 = x + x 24 = 2x then divide each side by two and you get 24/2 = 2x/2 simplified is 12 = x So x is 12 (blue marbles) and x + 2 is 14 is (the amount of red marbles). 12 + 14 = 26!
