Question

if P:Q = 1/2 : 1/3 and Q:R = 3/2 : 4/3, find P:R
the answer is 27:16, I need the process​

Answer 1

Step-by-step explanation:

We need to make Q value same in both ratios as it is common in both.

We can also write as P:Q =3/2 : 1

Q:R = 1 : 4/3*2/3 = 1 : 8/9

Now P:Q:R = 3/2 : 1 : 8/9

= 3*9 : 9*2 : 8*2

27 : 18 : 16
