Hope my answer helps you.

Answer 2

Let a = 2x

b = 3x.

Similarly,

b = 4y

c = 5y

c = 6z

d= 7z


From the above data, we can interpret that :

3x = 4y and 5y = 3z

Therefore,

y = [tex] \frac{3x}{4} and z = 5y/3 = [/tex]

Therefore,

z = (5 * 3x/4)/ 3

z = 5x/4

Now,

a = 2x

b = 3x

c = 5y = 15x/4

d = 7z = 35x/4

a : b : c : d

= 2x : 3x : 15x/4 : 35x/4

= 8 : 12 : 15 : 35

Hopefully this helps you.
