Question

if a : b is equal to 3 : 5 and b : C is equal to 10 : 13 find a:b:c ​

Answer 1

a:b=3:5=6:10

b:c=10:13

Hence

a:b:c= 6:10:13

Answer 2

A:B = 3:5 (1)

B:C = 10:13. (2)

So LCM of both values of B = 5 and 10 = 10

So multiply (1) by 2

So A:B:C

= 6:10:13 , which is in the simplest ratio
