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.

Use the image to answer the question.
An illustration shows a set of three adjacent rectangles labeled as Brayden. Another single rectangle is labeled Dominic and is placed below Brayden. All rectangles have the same dimensions. A bracket on the right side encompasses both sets and points to the number 48.
Brayden and Dominic both babysit on the weekend. This weekend Brayden and Dominic earned money in a ratio of 3:1
. If the boys earned a total of $48, how much did Dominic earn?

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.

To find the value of one rectangle shown in the tape diagram, we need to divide the total value (42) by the number of rectangles.
In this case, there are a total of 7 rectangles (3 Birds + 4 Dogs).
So, the value of one rectangle is:
42 / 7 = 6
Therefore, the correct answer is 6.

To determine how much money Henry will earn if he babysits for 5 hours, we can create a ratio table using the given information.
The table should list the number of hours and the corresponding amount of money earned.
Using the information provided, the ratio table should look like this:
Number of Hours Money Earned
1 $13
2 $26
3 $39
4 $52
5 $65
Therefore, if Henry babysits for 5 hours, he will earn $65.
So, the correct answer is:
Number of Hours Money Earned
1 $13
2 $26
3 $39
4 $52
5 $65

To complete the tables for the given ratios, we need to find the missing values A and B.
Looking at the ratio 5:9, we can see that if we multiply both numbers in the ratio by 2, we get the ratio 10:18.
Similarly, looking at the ratio 2:3, if we multiply both numbers in the ratio by 3, we get the ratio 6:9.
Therefore, the missing values A and B in the tables should be 10 and 18, and the correct answer is:
A = 10
B = 18
So, the correct response is:
A = 10 and B = 18.
not an option
Apologies for the incorrect response. Let's reevaluate the table using the given ratios.
The given ratios are 5:9 and 2:3. To find the missing values A and B, we can determine the relationship between the numbers in each ratio.
By multiplying the first ratio (5:9) by 2, we get 10:18. This suggests that A in the table should be 10 and B should be 18.
For the second ratio (2:3), if we multiply it by 2, we get 4:6. This suggests that A should be 4 and B should be 6.
Therefore, the correct answer is:
A = 4 and B = 6.
still wrong
Apologies for the confusion. Let's reevaluate the table using the given ratios.
The given ratios are 5:9 and 2:3. To find the missing values A and B, we need to maintain the same ratio relationship for both tables.
For the first ratio 5:9, we can see that if we multiply the first number by 2, the second number should also be multiplied by 2 to maintain the ratio relationship.
Applying this, we get:
A = 5 * 2 = 10
B = 9 * 2 = 18
For the second ratio 2:3, we apply the same logic:
A = 2 * 2 = 4
B = 3 * 2 = 6
Therefore, the correct answer is:
A = 10 and B = 18.
I apologize for the previous incorrect responses. Thank you for bringing it to my attention.
thats still not a option
Apologies again for the misunderstanding. Let's reevaluate the options provided.
Given the ratios 5:9 and 2:3, we can determine the missing values A and B in the tables.
Looking at the first ratio, if we multiply 5 by 2, we should also multiply 9 by 2 to maintain the ratio relationship.
Similarly, looking at the second ratio, if we multiply 2 by 3, we should also multiply 3 by 3 to maintain the ratio relationship.
Therefore, the correct answer should be:
A = 5 * 2 = 10
B = 9 * 2 = 18
I apologize that these values are not listed as options. Unfortunately, the correct answer is not provided among the given options. Again, I apologize for the confusion and any frustration caused.
the right answer is A = 6
and B = 9
.
Apologies for the confusion. You are correct.
To find the missing values A and B in the tables, we need to maintain the same ratio relationship between the numbers in the given ratios.
For the first ratio, 5:9, if we multiply the first number by 2, the second number should also be multiplied by 2 to maintain the ratio relationship. Thus, we get:
A = 5 * 2 = 10
B = 9 * 2 = 18
For the second ratio, 2:3, if we multiply the first number by 3, the second number should also be multiplied by 3 to maintain the ratio relationship. Hence, we have:
A = 2 * 3 = 6
B = 3 * 3 = 9
Therefore, the correct answer is:
A = 6
B = 9
