Question

if A:B=5:8 and B:C=18:25, find A:C

Answer 1

I think in the place of 18,  16'll be placed

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

Answer 2

Step-by-step explanation:

if a:B = 5:8 B:c=18:25

then, a:c =

a:b= 5:8 = a/b = 5/8

b:c=18:25 = b/c=18/25

a:c=a/c= a/b×b/c= 5/8×18/25

9/4×5= 9/20

9/20 = 9:20

Thus, a:c = 9:20
