I cant see the image...but I take it that the midpoint is (9,8) and the endpoint S is (10,10) and ur looking for the other endpoint R.
midpoint formula : (x1 + x2) / 2, (y1 + y2) / 2
(10,10)....x1 = 10 and y1 = 10
(x,y)....x2 = x and y2 = y
so we sub
(10 + x) / 2, (10 + y) / 2 = 9/8
(10 + x) / 2 = 9
10 + x = 9 * 2
10 + x = 18
x = 18 - 10
x = 8
(10 + y) / 2 = 8
10 + y = 8 * 2
10 + y = 16
y = 16 - 10
y = 6
so endpoint R has coordinates of (8,6) <===

She can make 19 batches of oatmeal.
EXPLANATION
First we can change the mixed number into an improper fraction:
![12\frac{2}{3}=12+\frac{2}{3}=\frac{12\cdot3}{3}+\frac{2}{3}=\frac{36}{3}+\frac{2}{3}=\frac{38}{3}](https://tex.z-dn.net/?f=12%5Cfrac%7B2%7D%7B3%7D%3D12%2B%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B12%5Ccdot3%7D%7B3%7D%2B%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B36%7D%7B3%7D%2B%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B38%7D%7B3%7D)
In this problem, r = 2/3. The division is:
![12\frac{2}{3}\div r=\frac{38}{3}\div\frac{2}{3}](https://tex.z-dn.net/?f=12%5Cfrac%7B2%7D%7B3%7D%5Cdiv%20r%3D%5Cfrac%7B38%7D%7B3%7D%5Cdiv%5Cfrac%7B2%7D%7B3%7D)
Using the KFC rule:
![\frac{38}{3}\div\frac{2}{3}=\frac{38}{3}\times\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B38%7D%7B3%7D%5Cdiv%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B38%7D%7B3%7D%5Ctimes%5Cfrac%7B3%7D%7B2%7D)
Solving we can see that the denominator of the first fraction can be simpliied with the numerator of the second fraction:
![\frac{38}{3}\times\frac{3}{2}=\frac{38}{1}\times\frac{1}{2}=\frac{38}{2}=19](https://tex.z-dn.net/?f=%5Cfrac%7B38%7D%7B3%7D%5Ctimes%5Cfrac%7B3%7D%7B2%7D%3D%5Cfrac%7B38%7D%7B1%7D%5Ctimes%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B38%7D%7B2%7D%3D19)
