Question

if 3a = 4 b =5C, find a : B :C​

Answer 1

3a = 4b

a/b = 4/3

a:b = 4:3

4b = 5c

b/c = 5/4

b:c = 5:4

Now,

a:b = 4:3

  b:c = 5:4

a:b:c = 5*4 : 3*5 : 3*4 = 20 : 15 : 12

Answer 2

Answer:

3a=4b

ab=3/4

a:b=3:4

,b=4=5c

b/c=4:5

b:c=4:5

next

a:b=4:3

b:c=4:5

4*5:,4*3:3*5=20:12:15
