A = Sock's weight b = Princess' weight c = Luna's weight
a : b = 4 : 5 b : c = 6 : 7
at this point, we have to change the 2 ratios (a : b and b : c) into one ratio (a : b : c) to do that, we have to change the ratio number so the number b in both ratio is the same
a : b = 4 : 5 = 24 : 30 b : c = 6 : 7 = 30 : 35 From that we can conclude that a : b : c = 24 : 30 : 35
Since we're looking for the ratio of Sock's weight to Luna's weight, it will be a : c = 24 : 35
