Given p : q = 5 : 2 and q : r = 4 : 3, find the ratio of p : q : r

p : q : r = 10 : 4 : 3

Step-by-step explanation:

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

p : q : r =

10 : 4 : 3

Step-by-step 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

           10 : 4 : 3
