Answer:
p : q : r =
10 : 4 : 3
Explanation:
to make q equal in the two equations :
p : q = 5 : 2 x4
p : q = 20 : 8
q : r = 4 : 3 x2
q : r = 8 : 6
So p : q : r =
20 : 8 :6
p : q : r = 10 : 4 : 3
Expressing the ratio in fractional form
= ( cross- multiply )
4r = 3q ( divide both sides by 4 )
r = q = × 2 =
Then
p : q : r
= 5 : 2 : ( multiply all parts by 2 )
= 10 : 4 : 3
