0.15 1.290 This is what i got 3/20 and 1290.90
=============
15/100 = 3/20
--------------------
1.290 = 1290/1000 = 258/200 = 129/100

First one is correct: .15=15%2F100=3%2F20

Second one: 1.290=1290%2F1000=129%2F100. 129 = 3 * 43 and 100 = 2 * 2 * 5 *5, i.e. no factors in common, so 129%2F100 is reduced to lowest terms.
