Math Help Please!!!!!

If a/b=2 and b/c=3/4, what is the value of c/a? Express your answer as a common fraction.

Hello Jmaster!

$\frac{a}{b}=2,\ a=2b\\ \frac{b}{c}=\frac{3}{4},\ c=\frac{4b}{3}$

$\frac{c}{a}=\frac{4b}{3\cdot 2b}$

$\frac{c}{a}=\frac{2}{3}$

b/a = 1/2  c/b = 4/3

b/a * c/b =   c/a = 1/2 * 4/3 = 4/6 =2/3
