Question

if a:b = 2:5 and b:c = 3:8, then find a:b:c​

Answer 1

Step-by-step explanation:

a : b = 2 : 5

a : b = 2*3 : 5*3

a : b = 6 : 15

b : c = 3 : 8

b : c = 3*5 : 8*5

b : c = 15 : 40

a : b : c = 6 : 15 : 40

Answer 2

Step-by-step explanation:

a:b=2:5

b:c=3:8

here, we have to make 'b' of 'a is to b' and 'b is to c' equal.

LCM of b1 and b2

LCM of 5 and 3 :- 15

a:b:c

2 : 5 -multiplying by 3

3 : 8 -multiplying by 5
