Show that 3.6123 (has a line over 123) is a rational number by writing it as a fraction of integers.
Let x=3.6123
Multiply by 10 to get
Equation A: 10x=36.123
Multiply the original by 10000 to get
Equation B: 10000x=36123.123
-------------
Subtract Equation A from Equation B to get:
9990x=36007
Then x=36007/9990
So, 3.16123 = 36007/9990
----------
