Question

If 3a=2b and 6b=5c find a:b:c

Answer 1

Given: The equality 3a=2b and 6b=5c

To find: Ratio of a:b:c = ?

Solution:

• Now we have given two equalities 3a=2b and 6b=5c

• So a/b = 2/3 and b/c = 5/6

• Now making b same, we get:

               2/3 x 5/5 = 10/15

               5/6 x 3/3 = 15/18

• So now we have b as 15.

• So a:b:c will be 10:15:18

Answer:

               So the ratio of a:b:c will be 10:15:18.
