Answer:
1 to 5
211 to 1500
11 to 300
Step-by-step explanation:
1.8 to 9 = 18/90 = 1(18)/5(18) = 1/5 = 1 to 5
2.11 to 15 = 211/1500 = 211 to 1500
3.30 to 90 = 330/9000 = 110/3000 = 11/300 = 11 to 300
If there are 19 red marbles in every 1 black marble, and there’s a total of 120 marbles, that means 120/19, is equal to nearly 6.3 black marbles, but since you can’t split a marble in half, it would mean that there are 6 black marbles in total. Since, 19 * 6 is 114 & there’s a remainder of 6 to approach the final answer of 120, meaning there are 6 black marbles in the bag.
