Many 'fractions' can be easily created using ratios of multiples of 30: Multiples:30 60 90 120 150 . . . Ratios:30/1, 60/2, 90/3, 120/4, 150/5 . . .
52 to 2 i think i had it on a test once
15/6=30/12=35/14=5/2 for example. Any fraction of the form 5n/2n where n is a whole number will produce an equivalent fraction, read ratio, to 15/6.
