Show work for 1.6 > 1.3

1.6 is let's say one pie and 6/10 of a pie and that's how much a baker made which is obviously more that 1 pie and 3/10 of a pie that the baker made. A process for that is 1.6 = 1 6/10 = 16/10 and if u cross multiply that by 1.3 = 1 3/10 = 13/10 the value in the 16/10 side will be 160 which is more that the value on the 13/10 side which is 130
