The bag of marbles contains 20 red marbles 30 white marbles and 40 blue marbles what is the ratio of red to blue marbles?
If there are 20 red marbles and 40 blue marbles, the ratio of red to blue is 1 over 2. The number of white marbles does not matter.
A sack contains red and blue marbles The ratio of red marbles to blue marbles is 4 3 If there are 16 red marbles in the sack how many blue marbles are in the sack?
12 blue marbles
A bowl contains a total of 26 blue and red marbles There are two more red marbles than blue marbles How many blue marbles are in the bowl?
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!
A sack contains red and blue marbles The ratio of red marbles to blue marbles is 43 If there are 16 red marbles in the sack how many blue marbles are in the sack?
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
