Question

Ifa:b=3:7 and b:c = 4:9, find a:b:c.​

Answer 1

Answer:

12:28:63

Step-by-step explanation:

a:b = 3:7

b:c = 4:9

To find out a:b:c, we have to first find the LCM of 7 and 4 (the different given values of B)

The LCM of 4 and 7 = 28, so we have to multiply a:b by 4 and b:c by 7

Hence,

a:b = 12:28

b:c = 28:63

so ABC = 12:28:63

Answer 2

If a:b=5:9 and b:c=4:7 find a:b:c

This is an example!!!
