Question

If A:B=2:3, B:C=4:5 and C:D=6:7, then A:B:C:D is ? pls ans this question it's urgent

Answer 1

Answer:

16:24:30:35

Step-by-step explanation:

First...find B:C:D

B:C = 4:5

C:D = 6:7

Taking the LCM of both C's i.e., 5 and 6 = 30

Make both C as 30

B:C = 4×6:5×6 = 24:30

C:D = 6×5:7×5 = 30:35

Then ....

B:C:D = 24:30:35

Now here the value of B is 24...

Hence make B=24 in A:B

A:B = 2×8:3×8 = 16:24

Therefore....

A:B:C:D = 16:24:30:35
