35 & 49
The multiples of 5 between 30 & 50 which are odd are:
5 x 7 = 35
5 x 9 = 45
So for a ratio of 5 : 7, whatever the 5 is multiplied by the 7 must also be multiplied by:
7 x 7 = 49
7 x 9 = 63
63 is greater than 50, so multiplying 5 and 7 by 7 gives the solution of 35 & 49:
35 : 49 is the same ratio as 5 : 7
