Question

if A:B=5:8 and B:C=16:25,find A:C

Answer 1

Hi ,

A : B = 5 : 8 --- ( 1 )

multiply equation ( 1 ) with 2

A : B = 10 : 16

B : C = 16 : 25

Therefore ,

A : B : C = 10 : 16 : 25

A : C = 10 : 25

= 2 : 5

I hope this helps you.

Answer 2

a:b = 5:8 &b:c = 16:25.
In both values of only b are different.
Therefore we have to make values of b same.
B = 8 and 16 and 8*2 = 16
Therefore,since 8needs to be multiplied into 2,
5 will also be multiplied by 2.
5:8 converted to 10 (because5*2):16(because8*2).
so a:c = 10:25
