The ratio of 4 blue marbles to 6 white marbles can be said as 4:6, 4 to 6, or 4/6. This can then be simplified to 2:3 by a factor of 2.
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.
45 __ 91
Total number of marbles in the bag = 6 + 19 + 5 + 19 + 17 = 66Number of yellow ones = 19If drawing perfectly randomly, then the probability of pulling a yellow one = 19/66 = 28.8% (rounded)
it is 6/9 simplifyyou get 2/3.

Four. The answer will be 12 to 6 which reduced is 2 to 1.
11 marbles total and 6 are blue so probability is 6/11
0No blue marbles in the bag.
Because 1/3 are blue and 1/2 are red and the rest are green we can calculate that 1/6 of the marbles are green. 1/3 = 2/6 1/2 = 3/6 2/6 + 3/6 = 5/6 which leaves 1/6 green. Since there are 7 green marbles we know there must be 7 x 6 total. The answer is 42 marbles.
