What is the number of each colour of marbles in a bag of 76 marbles if the ratio of red marbles to green marbles is 2 to 3 and the ratio of green marbles to blue marbles is 9 to 4?
The ratios are: red : green = 2 : 3 = (2×3) : (3×3) = 6 : 9 green : blue = 9 : 4 → ratio of red : green : blue = 6 : 9 : 4 There are 6 + 9 + 4 = 19 parts 76 marbles ÷ 19 parts = 4 marbles per part → red: 6 parts = 6 × 4 marbles per part = 24 red marbles → green: 9 parts = 9 × 4 marbles per part = 36 green marbles → blue: 4 parts = 4 × 4 marbles per part = 16 blue marbles To check: red + green + blue = 24 marbles + 36 marbles + 16 marbles = 76 marbles in the bag.

The ratio of red marbles to blue marbles was 5 to 4 if there were 225 in all how many were blue marbles?
The ratio tells us that for every 5 red marbles there are 4 blue ones. Now the total number is 225. Out of 9 total marbles, we know 4 are blue. So we can look at 4 blue/9 total= (x blues which we want to know)/ 225. This is not hard to solve by cross multiplication. 9x=4(225) or 9x=900 so x is 100 and there are 100 blue marbles. Now if that is so, we know the rest of the marbles must be red so there are 225-100=125 red ones. Let us check that this ratio is 5/4 as desired. Red/Blue=125/100 and 25 goes into 125 5 times and into 100 4 times so this becomes 5/4. How else would we do this problem. Since the ratio of 5/4, we know as we said above there are 4/9 blue marbles ( every 4 marbles out of 9 is blue). Now 4/9(225)=4x225/9=100.

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
What is the number of each colour of marbles in a bag of 76 marbles if the ratio of red marbles to green marbles is 2 to 3 and the ratio of green marbles to blue marbles is 9 to 4?
The ratios are: red : green = 2 : 3 = (2×3) : (3×3) = 6 : 9 green : blue = 9 : 4 → ratio of red : green : blue = 6 : 9 : 4 There are 6 + 9 + 4 = 19 parts 76 marbles ÷ 19 parts = 4 marbles per part → red: 6 parts = 6 × 4 marbles per part = 24 red marbles → green: 9 parts = 9 × 4 marbles per part = 36 green marbles → blue: 4 parts = 4 × 4 marbles per part = 16 blue marbles To check: red + green + blue = 24 marbles + 36 marbles + 16 marbles = 76 marbles in the bag.
