Question

2. If P: Q = 4 : 5 and Q : R = 6: 7, find the
following ratios:
9. P:Q:R
b. P: R​

Answer 1

Answer:

P : Q : R = 24 : 30 : 35

and, P : R = 24 : 35

Step-by-step explanation:

P:Q= 4:5......(1)

Q:R= 6:7,......(2)

Multiply (1) by 6 and (2) by 5 to make Q identical we get,

P:Q= 24:30

Q:R = 30: 35

So, P : Q : R = 24 : 30 : 35

and, P : R = 24 : 35
