If the ratio of children to parents is 3 to 2 which of these shows possible numbers of children to parents?
A.60 children 90 parents
B.169 children 112 parents
C.112 children 169 parents
D.170 children 115 parents
B?
There are 2 men teachers to every 5 women teachers at Lamar Middle School. There are exactly 24 men on the faculty of Lamar. Which proportion can be used to find W, the number of women teachers at Lamar?
A.
2/5=W/24
B.24/2=5/w
C.24/w=5/2
D.2/5=24/w
D?
You're close on the first one, but none of the answers are correct. Check for typos in the problem.
The second one is correct.
168 children and 112 parents for B
Right.
It is a . Because ratios not only have to always be even
To determine which of the given options shows possible numbers of children to parents in a ratio of 3 to 2, we can calculate the ratio for each option and compare it to 3:2.
Let's calculate the ratios for each option:
A. 60 children to 90 parents
Ratio = 60/90 = 2/3
B. 169 children to 112 parents
Ratio = 169/112 = 1.51
C. 112 children to 169 parents
Ratio = 112/169 = 0.66
D. 170 children to 115 parents
Ratio = 170/115 = 1.47
Based on the calculations, none of the given options show a ratio of 3 to 2. Therefore, the correct answer is none of the options provided.
Now let's move on to the second question:
The problem states that the ratio of men teachers to women teachers at Lamar Middle School is 2 to 5, and there are exactly 24 men on the faculty.
To solve for the number of women teachers, we can set up the following proportion:
2/5 = 24/W
Here, W represents the number of women teachers.
Now we can solve for W by cross-multiplying:
2W = 5 * 24
2W = 120
Dividing both sides by 2 gives:
W = 120/2
W = 60
Therefore, the correct proportion to find the number of women teachers at Lamar is:
Option A: 2/5 = W/24
So, the correct answer to the second question is A.
