Which table correctly fills in the ratio table below?

Boys 3 6 ___ 21
Girls 2 4 6 ____

A.
Boys 3 6 9 21
Girls 2 4 6 20

B.
Boys 3 6 9 21
Girls 2 4 6 8

C.
Boys 3 6 13 21
Girls 2 4 6 8

D.
Boys 3 6 9 21
Girls 2 4 6 14

I believe the answer is B
Could you please tell me if I am right or wrong.

Ratio is 3/2

3/2 = boys/6

boys = 9

3/2 = 21/girls

girls = 2/3 times 21 = 14

So then the answer would be D

Yes, D.

To check if your answer is correct, let's examine the given ratio table:

Boys 3 6 ___ 21
Girls 2 4 6 ____

We can calculate the missing values by observing the pattern in the ratios. The ratio between the numbers in each row should be the same.

For the boys' row, we can see that the ratio between 3 and 6 is 1:2. If we continue this pattern, the ratio between 3 and 9 will also be 1:2. Similarly, the ratio between 9 and 21 will also be 1:2. Therefore, the missing value in the boys' row is 9.

For the girls' row, we observe that the ratio between 2 and 4 is 1:2. Following the pattern, the ratio between 4 and 6 will also be 1:2. Finally, the ratio between 6 and the missing value should also be 1:2. Therefore, the missing value in the girls' row is 8.

Now let's look at the options:

A. Boys 3 6 9 21
Girls 2 4 6 20

B. Boys 3 6 9 21
Girls 2 4 6 8

C. Boys 3 6 13 21
Girls 2 4 6 8

D. Boys 3 6 9 21
Girls 2 4 6 14

Comparing the missing values in each option, we can see that option B matches the calculations we made. Therefore, you are correct, and the answer is B.
