I think this is just combining ratios soo..
P:q
3/4:2

P : Q : R
3/4 : 2. :
1/3. : : 1/2
————————-
1/3. : 4.5 : 1/2

3/4X 1/3= 4/12=1/3
3/4 / 1/3= 9/4= 2.25
2 X 2.25= 4.5

The ratio is

1/3 : 4.5 : 1/2

Answer:

3/8

Explanation:


(p)/(q) = ( (3)/(4) )/( (2)/(1) ) \\ (p)/(q) = (3)/(8)


(p)/(r) = ( (1)/(3) )/( (1)/(2) ) \\ (p)/(r) = (2)/(3)


( (p)/(q) )/(r) = ( (3)/(8) )/( (2)/(3) ) \\ ( (p)/(q) )/(r) = (9)/(16) = (3)/(8)
