Hi, Daniel.
(Hope my maths is right!!)
Almost.
maybe 7 and 11/16 divided by 3 and 7/8 and I'd call out 1 and 51/62.
7 * 16 = 112 + 11 = 123/16
(3 * 8 = 24 + 7 = 31) * 2 = 62/16
123 - 62 = 61
So you should have said 1 and 61/62.
If MY math is right. ;^}
(Win8's Calculator says 123 / 62 = 1.983870967741935.)

If I have a pocket full of coins, I'll often do this as well! On at
least one occasion, with older style till's I think, I've been given
change of $0.77 plus $1.23. Seems some people don't really look at what
is going on!
On a Mathematical bent, between 1985 and 1995, I was an Electronics
teacher at an Australian Army Trade School, and, at one time I was
teaching a Circuit Analysis subject dealing with
Thevinin's/Norton/Kirchoff's/Etc. Theromyns.
At one time, having finished "teaching" the subject, I was drawing up
circuits on the "blackboard" for the students to solve. One that I drew
up had six interconnected circuit loops, requiring six simultaneous
equations to solve! Didn't take me long to realise that I had no idea
how to solve six simultaneous equations, let alone for the students to
manage anything.
Not a problem .... I went off to the General Education section and got
one of the Education Corps Captains to come over and help me/us out. So
he started working his way through the six equations, multiplying one
equation so that one of the numbers would be equal to a figure in
another equation, which allowed substitution and "normal" simultaneous
equations processes, again and again and again.
I was standing at the back of the room, helping out with the divisions
in the sum, e.g. it might have needed 2 and 1/3 divided by 1 and 3/4,
and I would call out 1 and 1/3.
As the equations were sorted out, the numbers got nastier and nastier,
maybe 7 and 11/16 divided by 3 and 7/8 and I'd call out 1 and 51/62.
Wasn't long before most of the class had turned around looking at me do
all this *mental* arithmetic.
Ahh!! The good old days!! Made me remember to pre-prepare any problems I
set the students
Any body remember "Four Figure Log books"??
(Hope my maths is right!!)
