Answer 3

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.

Answer 4

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.
