Question

If a:b is 2:5 and b:c is 3:4, find a:b:c

Answer 1

just keep in mind am not sure if the answer 6:15:20

Explanation:

now we have ab= 2 : 5

and bc= 3 : 4

so b is the common one between them so multiply both of the b together which will give u 15 so now we have b = 15

to get a multiply 2 by 3 to get 6 so a = 6

to get c multiply 4 by 5 to get 20 so c = 20

now I hope that its correct and that u understood
