3.25 - 1.80 = 1.45 = 1 45/100 = 1 9/20 Sorry, it doesn't actually take that long. I was just playing with other ways to do it.
This is the easiest way to do it IMO

ok lol
is that 1(45/100) and 1(9/20)
Yes they are mixed fractions
k
The other trick way to do it is this:
wait
that is hours so what would it be in seconds
3 1/4 - 1 4/5 (3 - 1) - (1/4 - 4/5) 2 - (5/20 - 16/20) 2 - (11/20) 2 - 11/20 40/20 - 11/20 = 29/20
29/20 = 1 9/20
that is hours so what would it be in seconds
Don't convert it into seconds
just convert it into hours and minutes
oh ya it says minutes my mistake
so howd u do that
Well you know an hour is 60 minutes, so that takes care of the 1. For 9/20, set up a proportion: 9/20 = x/60 cross multiply: 20x = 540 x = 540/20 x = 54/2 x = 27 minutes So 1 hour and 27 minutes or 60 + 27 = 87 minutes
