For
example, to change 3/4 to such a fraction I clone
(multiply the numerator and denominator) 3/4 by 25
and like magic, I have, 75/100. I like doing this
except it gets awfully tiresome to have to keep on
writing the slash 100 all the time. So being as
clever as I am, I invented a shortcut. Instead of
writing 75/100, I write point 75. It looks like
this: .75.
23/100 looks like .23 while 3/100 looks like .03, and so on."
"I get it," said 4/6. "So what would 3 1/2 look like as a decimal?"
"Since you have a whole part you write that before the decimal point. Then you clone 1/2's form to 5/10. So 3 5/10 becomes 3.5," replied 1/4.
Note: Actually John Napier pioneered the use of a decimal point in the 17th century.1 But we won’t tell Joe.
