There are two ways:
1.
2.
How'd I get that?
I knew it has to be a 4-digit number on top and
a 5 digit number on the bottom. I knew that
has to be close. The numerator has to be increased or
decreasd with the denominator always being 3 times the
numerator, so that we don't use the same digit twice
or any zeros.
I used a TI-84 calculator.
I pressed CLEAR
I pressed Y=
After \Y1= I typed 3X
I pressed 2ND
I pressed Window
I made this menu read
TABLE SETUP
TblStart=6000
ᅀTbl=1
Indpnt: Auto Ask
Depend: Auto Ask
with "Auto" highlighted in both places
then
I pressed 2ND
I pressed GRAPH
Then I pressed the up arrow looking under the X and the Y1
columns until I got to a case where all 9 digits appeared.
It didn't take me long to find those two that way.
