Question

if 3A=2B=5C,then find A:B:C

Answer 1

let 3A = 2B = 5C =k

3A = k implies A = k/3

2B= k implies B = k/2

5C =k implies C = k/5

A:B:C = K/3 :K/2: K/5
             = 1/3:1/2:1/5
             = 30/3 :30/2 : 30/5  MULTIPLY EACH TERM WITH 30
              = 10:15:6

Answer 2

let 3A = 2B = 5C =k

3A = k implies A = k/3

2B= k implies B = k/2

5C =k implies C = k/5

A:B:C = K/3 :K/2: K/5

            = 1/3:1/2:1/5

            = 30/3 :30/2 : 30/5  MULTIPLY EACH TERM WITH 30
