Question

a:b is 1:2, b:c is 3:2 , c:d is 1:3 , find a:b:c:d​

Answer 1

Answer:

A:B:C:D = 3:6:8:12

Step-by-step explanation:

There is a simple way of doing these kind of problems by multiplying both sides with multiples of a number make a paticular variable common in both the ratio

A:B = 1:2 , B:C = 3:4

Now multiply A:B with 3 and multiply B:C with 2

Then A:B = 3:6 and B:C = 6:8

Now combining both A:B:C = 3:6:8

Again C:D = 6:9

Now multiplying A:B:C with 3 and C:D with 4

Then A:B:C = 9:18:24

and C:D = 24:36

Now combining the above two

A:B:C:D = 9:18:24:36

Again D:E = 12:16

Now by multiplying A:B:C:D by 1 and D:E by 3 we get,

A:B:C:D = 9:18:24:36

and D:E = 36:48

So again combining the above two

A:B:C:D:E = 9:18:24:36:48

Since the above ratio is a multiple of 3 so after division:-

A:B:C:D = 3:6:8:16
