Question

If 3a=11b and b= 2c, find the ratio of a:b, a:b:c

Answer 1

Answer:

a:b = 11:3 and a:b:c = 11:3:2

Step-by-step explanation:

a:b is equal than write a/b. So a/b=11/3 it means a:b = 11:3

b:c is then b/c = 2

For a:b:c the ratio must be maintained. Ratio is equals reasons or divides. We already know a:b is 11:3. What about a:c?

3a=11b then a=11/3 b, b=2c then c=1/2 b hence a/c =22/3 if we pay attention this reason is 2*11/3 so a:b:c is 11:3:2
