Question

If 2a = 3b and 5b = 6c, then what is the value of a : b : c?

Answer 1

Answer:

10:15:18

Step-by-step explanation:

2a=3b    

5b=6c

5(2a=3b)

10a=15b

5b=6c

3(5b=6c)

15b=18c

10:15:18

Answer 2

Answer:

a:b:c = 18:12:10

Step-by-step explanation:

2 a = 3 b                                   5 b = 6 c

or, a/b = 3/2                             or, b/c = 6/5

B should be common......so,

3/2 =  3 x 6/2 x 6 = 18/12

6/5 = 6 x 2/5 x 2 = 12/10

∴ a:b:c = 18:12:10
