how many orange marbles?
To find the ratio of each colored marble to the total number of marbles, we need to divide the number of each colored marble by the total number of marbles.
Number of red marbles: 12
Number of blue marbles: 19
Number of orange marbles: unknown
Total number of marbles: 40
Ratio of red marbles to total marbles: 12/40 = 3/10
Ratio of blue marbles to total marbles: 19/40
Since we do not know the number of orange marbles, we cannot simplify the ratio further.
Therefore, the ratios are:
Ratio of red marbles to total marbles: 3/10
Ratio of blue marbles to total marbles: 19/40
To find the ratio of each colored marble to the total number of marbles in the jar, you need to first add up the number of red and blue marbles.
The total number of red and blue marbles is 12 + 19 = 31.
Next, you can find the ratio of each colored marble to the total number of marbles using the following steps:
1. Ratio of red marbles to the total number of marbles:
Red marbles: Total marbles = 12 : 40.
This ratio can be simplified by dividing both numbers by their greatest common divisor (GCD), which is 4.
Simplified ratio: 3 : 10.
2. Ratio of blue marbles to the total number of marbles:
Blue marbles: Total marbles = 19 : 40.
This ratio cannot be simplified further as there is no common factor to divide both numbers by.
3. Ratio of orange marbles to the total number of marbles:
To find the number of orange marbles, subtract the total number of red and blue marbles from the total number of marbles:
Orange marbles = Total marbles - (Red marbles + Blue marbles)
= 40 - (12 + 19)
= 40 - 31
= 9.
Orange marbles: Total marbles = 9 : 40.
This ratio cannot be simplified further as there is no common factor to divide both numbers by.
Therefore, the ratio of each colored marble to the total number of marbles in the jar is:
Red marbles: Total marbles = 3 : 10.
Blue marbles: Total marbles = 19 : 40.
Orange marbles: Total marbles = 9 : 40.
