K = 4pq^2
k/4p = q^2
0.5(k/p)^1/2 = q
You have to draw the numbers then you would have to divide them draw it
you would change the denominators to the least common multiple, in this case, 12. then you would change the fractions to 8/12, 14/12, and 7/12. you would add those, and get 29/12. divide 29 by 12, and get 2. add the rest to get 2 5/12.

3 + 1.5 = 4.5
4.5 + 1.5 = 6
6 + 1.5 = 7.5
