"What?" asks .4 Complex
fractions? What are you talking about? 7/10ths who was in
the crowd had an "aha" moment and said "Look at result.
How do you read that?" "Why, 65 hundredths said the Mayor.
But that's what I would say in the 'burg interrupts point
4 and I would write it as .65 So point 65 is the same as 65/100 said the Mayor. That's between .6 and .7 and it would pop the balloon. *For those of you that are reading this story, you might want to check out this website to learn more about decimals and place values.

When they were done
playing, Mayor One was energized. "Now I understand better
how decimal numbers work. The numbers after the decimal
point tell you how many fractional pieces of tenths,
hundreds, thousandths, etc. there are. So, for example, if
you add a number, say 3, after the 1 in .1 you have .13
which increases .1 (1/10) by 3/100. That means that 1/10
cloned by 10 (10/100) added to 3/100 is 13/100 or .13"
Four-sixths listening intently, scratched his head and
said, "If you say so. I'm going to go back to the decimal
darts game and practice some more." Meanwhile, one of the fractions spotted the Burgerama and said it was time to eat. So off they went. Four-sixths |

on the other hand, walked
over to the information booth to listen to Joe "Four"
Decimalis. Joe: One of my hobbies is is to change all fractional numbers into a fraction with a denominator of 10, 100, 1000, etc. For example, to change 3/4 to such a fraction I immediately clone (multiply the numerator and denominator) 3/4 by 25 and presto, I have, 75/100. I like doing this except it gets awfully boring 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: 23/100 looks like .23 while 3/100 looks like .03, and so on. "I get it," said four-sixths. "So what would 3.5 be as a fraction? "If you have a number before the decimal point you treat it as a whole number. So 3 point 5 is 3 wholes and 5 tenths. (In decimal notation you don't reduce fractions.) |
