Question

three numbers a, b, c are such a:b =2:3 and b:c= 4:5 then ratio between a:b:c​

Answer 1

Answer:

We are given with two simple ratios

a:b=2:3,

b:c=4:5

When we want the combined ratio of these kind of ratios like a:b:c, we do have a small trick.

In a:b:c the ratio component of ‘a’ will be the product of compnent of ‘a’ in a:b and component of ‘b’ in b:c I.E., 2*4=8. a=8.

Component of ‘b’ will be product ‘b’ components in both the ratios I.E., 4*3=12. b=12

Component of c will be product of Component of b in a:b and c component in b:c I.E., 5*3=15. C=15

Explanation:

Answer 2

Answer:

☆ - a:b:C = 8:12:15

Explanation:

the common factors 3 & 4is 12

a:b=2:3=(2*4):(3*4)=8:12

a:b =8:12

again, b:c = 4:5=(4*3):(5*3)= 12:15

b:C = 12:15

therefore, a:b:c= 8:12:15
