To determine how many marbles are in a jar if 8 of them are blue, we can use the given ratio of 2 blue marbles for every 5 total marbles.
By setting up a proportion, we can solve for the missing value in the table:
2 blue marbles / 5 total marbles = 8 blue marbles / x total marbles
Cross-multiplying and solving for x, we get:
2x = 8 * 5
2x = 40
x = 20
Therefore, if 8 of the marbles in the jar are blue, then the total number of marbles in the jar is 20.
Use the table to answer the question.

To determine the missing values in the ratio table:
For the second row, there are 4 blue marbles. Using the given ratio of 2 blue marbles for every 5 total marbles, we set up a proportion:
2 blue marbles / 5 total marbles = 4 blue marbles / x total marbles
Cross-multiplying and solving for x, we get:
2x = 4 * 5
2x = 20
x = 10
Therefore, if 4 of the marbles in the jar are blue, then the total number of marbles in the jar is 10.
For the third row, there are 6 blue marbles. Again, using the given ratio of 2 blue marbles for every 5 total marbles, we set up a proportion:
2 blue marbles / 5 total marbles = 6 blue marbles / x total marbles
Cross-multiplying and solving for x, we get:
2x = 6 * 5
2x = 30
x = 15
Therefore, if 6 of the marbles in the jar are blue, then the total number of marbles in the jar is 15.
For the second row, there are 4 blue marbles. Using the given ratio of 2 blue marbles for every 5 total marbles, we set up a proportion:
2 blue marbles / 5 total marbles = 4 blue marbles / x total marbles
Cross-multiplying and solving for x, we get:
2x = 4 * 5
2x = 20
x = 10
Therefore, if 4 of the marbles in the jar are blue, then the total number of marbles in the jar is 10.
For the third row, there are 6 blue marbles. Again, using the given ratio of 2 blue marbles for every 5 total marbles, we set up a proportion:
2 blue marbles / 5 total marbles = 6 blue marbles / x total marbles
Cross-multiplying and solving for x, we get:
2x = 6 * 5
2x = 30
x = 15
Therefore, if 6 of the marbles in the jar are blue, then the total number of marbles in the jar is 15.
