Question

(pa+qc+re)/(pb+qd+rf)

Answer 1

Answer:

1:2

Step-by-step explanation:

If a:b=c:d=e:f=1:2

1 : 2

a/b = c/d = e/f = 1/2

pa/pb = qc/qd = re/rf = 1/2                       multiplying and dividing first term by p

                                                                                   second term by q and

                                                                                     third term by r

(pa+qc+re) / (pb+qd+rf) = 1/2
