this is the problem:
Assume that m varies inversely with n. If m=6 when n=2/3, what is the value for m when n=15? Write the equation, find k the constant of proportionality, and solve.

im not confident with my answer but this is what i got..

n=15 m=x
15 / 2/3 = 22.5=K
22.5 x 6=135

$$\displaystyle m=\frac{k}{n}$$

$$\displaystyle 6=\frac{2k}{3}$$

$$\displaystyle k=\frac{(3)6}{2}=9$$

$$\displaystyle m=\frac{9}{n}=\frac{9}{15}=\frac{3}{5}$$

Inverse proportion means....
one variable increasing causes the other to decrease and vice versa.
