80 blue
120 - 80 = 40 red
40 / 80 = ????
divide top and bottom of the fraction by 40
To find the ratio of red to blue marbles, we need to determine the number of red marbles in the bag.
Given that the bag contains 120 marbles in total and 80 of them are blue, we can find the number of red marbles by subtracting the number of blue marbles from the total number of marbles.
Number of red marbles = Total number of marbles - Number of blue marbles
Number of red marbles = 120 - 80
Number of red marbles = 40
Therefore, there are 40 red marbles in the bag.
Now, to calculate the ratio of red to blue marbles, we can express it as a fraction or a ratio.
Ratio of red to blue marbles = Number of red marbles / Number of blue marbles
Ratio of red to blue marbles = 40 / 80
Simplifying this ratio gives:
Ratio of red to blue marbles = 1 / 2
Hence, the ratio of red to blue marbles is 1:2 or 1/2.
