Question

if P :Q = 7 : 4 and Q :R = 5 :14 then find P :Q : R​

Answer 1

Step-by-step explanation:

p:Q =7:4

Q:R = 5:14

P :Q:R = 35:20:56

( cross and straight multiply )

Answer 2

P:Q=7:4   =R1

Q:R=5:14   =R2

We have to multiply both the ratios so that their Q becomes equal

Multiply ratio 1 by 5 (Q is 5 in the other equation)

R1=  P:Q=35:20

Same for R2, but here by 4

R2=  Q:R=20:56

P:Q:R=35:20:56
