12: 18 :: 2 : 3
NB '6' is a common factor so reduce by '6'.
NNB Instead of writing 'as/to' all the time, mathemticians use a colon ':' , and a double colon ( :: ) for the reduced comparsion.
70:2 is one example. It is a ratio of the from 35*k/k where is any non-zero number.
6/16 is equivalent to 3/8 or 12/32, 18/48
912/1 is one equivalent ratio.
5/6 is equivalent to 10/12 and 15/18
18/8 and 27/12
120 to 180 is an equivalent ratio.
12 × ratio = -18 → ratio = -18/12 = -3/2 = -1.5 Checking: -18 × ratio = -18 × -3/2 = 27 as required The common ratio is -3/2 (or -1.5)
