To find the ratio of sisters to brothers, we need to compare the number of sisters to the number of brothers.
In this case, there are 4 sisters and the rest are brothers.
So, the ratio of sisters to brothers is 4:8.
The correct answer is 35 to 20, which represents the ratio of 35 vegetables to 20 carrots.
To find the ratio of sisters to brothers, we will use the formula: Ratio = Number of Sisters : Number of Brothers.
In this question, we are given that there are 12 total siblings, and 4 of them are sisters. Therefore, the ratio of sisters to brothers is 4: (12-4), which simplifies to 4:8.
So, the correct answer is: 4:8.

To find the whole-to-part ratio for the total refreshments to boxes of orange juice, we need to divide the total number of refreshments by the number of boxes of orange juice.
In this case, there are 13 lemonades, 14 bottles of water, and 12 boxes of orange juice, so the total number of refreshments is 13 + 14 + 12 = 39.
Therefore, the whole-to-part ratio for the total refreshments to boxes of orange juice, written as a fraction, is 39/12.
So, the correct answer is Start Fraction 39 over 12 End Fraction.

To find out how much Dominic earned, we need to determine what fraction of the total earnings he had based on the given ratio.
The ratio between Brayden and Dominic's earnings is given as 3:1. This means that for every unit of Dominic's earnings, Brayden earns 3 units.
Since the total earnings of both boys is $48, we can represent this situation with the equation:
3x + x = 48
Combining like terms, we have:
4x = 48
Dividing both sides by 4, we find:
x = 12
This means that Dominic earned $12.
So, the correct answer is $12.
