The ratio of guests under 15 to the total number of guests is 1:2. How many guests are under 15? The answer is five. Am I correct.

Over 65 2
No. The "total" includes everyone including those under 15.
1/2 = x/(11+x)
5.5 + .5x = x
5.5 = .5x
11 = x
Thus there are 11 under 15 and 22 total.
Based on the information provided, we cannot determine the exact number of guests under 15 since the table does not specify the number of guests for the "Under 15" age range. However, if the ratio of guests under 15 to the total number of guests is 1:2, we can calculate an estimate.
Let's denote the total number of guests as "T". According to the ratio, the number of guests under 15 would be (1/3)T, since the total ratio is 1:2:3 (1 part for under 15, 2 parts for 15-40, and 3 parts for 41-65 and over 65 combined).
To find an estimate for the number of guests under 15, we need to calculate (1/3)T using the given number of guests in the age ranges 15-40, 41-65, and over 65.
Using the provided table:
Number of guests between 15-40 = 6
Number of guests between 41-65 = 3
Number of guests over 65 = 2
Total number of guests = (6 + 3 + 2) = 11
Estimate for the number of guests under 15 = (1/3) * 11 = 11/3 ≈ 3.67
Therefore, based on the given information, it appears that the answer of five guests under 15 is not correct.
To find the number of guests under 15, you need to compare the ratio of guests under 15 to the total number of guests.
In this case, the ratio is given as 1:2. This means that for every 1 guest under 15, there are 2 guests in total.
To find the number of guests under 15, you can set up a proportion:
(Number of guests under 15) / (Total number of guests) = 1/2
Since the total number of guests is not given in the table, we can calculate it by adding up the number of guests in each age range.
Based on the provided table, the total number of guests is:
6 (guests aged 15-40) + 3 (guests aged 41-65) + 2 (guests over 65) = 11
Now, we can substitute the values into the proportion:
(Number of guests under 15) / 11 = 1/2
To solve for the number of guests under 15, we can cross multiply:
2 * (Number of guests under 15) = 11 * 1
2 * (Number of guests under 15) = 11
(Number of guests under 15) = 11 / 2
(Number of guests under 15) = 5.5
Based on this calculation, we find that the number of guests under 15 is 5.5, not 5. Since the number of guests cannot be a fraction, the correct answer is that there are approximately 5 guests under 15.
