If p:q=2:3 and q:r=4:5,find p:q:r

Answer»

Hi ,

P : Q = 2 : 3

p : q = ( 2 × 4 ) : ( 3 × 4 )

= 8 : 12 ----( 1 )

q : r = 4 : 5

q : r = ( 4 × 3 ) : ( 5 × 3 )

= 12 : 15 ----( 2 )

Therefore ,

From ( 1 ) and ( 2 ) ,

p : q = 8 : 12

q : r = 12 : 15

p : q : r = 8 : 12 : 15

I HOPE this helps you.
