Answer:
8
Step-by-step explanation:
A = 64 musicians
A*5/8 = 40 guitarists
Jazz: x
Classic: y
x=4y
x + y = 40
5y = 40
y = 8
By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is ![\frac{5y_2+y_1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5y_2%2By_1%7D%7B6%7D)
<h3>What is section formula ?</h3>
Let point P(x,y) cuts line joining point
and
in
then coordinate of point P is equal to ![(\frac{m_1x_2+m_2x_1}{m_1+m_2}, \frac{m_1y_2+m_2y_1}{m_1+m_2})](https://tex.z-dn.net/?f=%28%5Cfrac%7Bm_1x_2%2Bm_2x_1%7D%7Bm_1%2Bm_2%7D%2C%20%5Cfrac%7Bm_1y_2%2Bm_2y_1%7D%7Bm_1%2Bm_2%7D%29)
Here given that point divides line segment from J to K into a ratio 5:1
So
![m_1=5\\\\m_2=1](https://tex.z-dn.net/?f=m_1%3D5%5C%5C%5C%5Cm_2%3D1)
Now we have to fin y coordinate of point that divides the directed line segment from J to K into a ratio of 5:1
We can calculated y coordinate by applying section formula as :
![\frac{5y_2+1y_1}{5+1}\\\\\frac{5y_2+y_1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5y_2%2B1y_1%7D%7B5%2B1%7D%5C%5C%5C%5C%5Cfrac%7B5y_2%2By_1%7D%7B6%7D)
By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is ![\frac{5y_2+y_1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5y_2%2By_1%7D%7B6%7D)

Answer: 4 and 1/2
Step-by-step explanation: Ok so 12 is a whole number so to turn it into a fraction put it over one as in 12/1.
Then just multiply 12/1 x 3/8 which equals 36/8 But we aren't done!
now we must calculate how many times 8 goes into 36 without going over 36 which is 4. 8 times 4 is 32 so we have 4 leftover. Now writing this as a fraction is 4 4/8. 4 is the whole number and that 4 represents 8 going tinto 36 4 times like we just demonstrated. since 36-32 is 4 thats how you get a 4/8 as your fraction.
Then you just simplify your fraction and 4 4/8 turns into just 4 1/2.
I really hope I explained this well and you understand it! :)
