I'm sure you are hungry by now. So is Mayor 1 and he's waiting for you to go in. Here's today's special at the Fracteria. Soda:
$ 1/2
Burger: $ 1 1/8 Fries: $ 3/4 Mayor 1 is
stumped. He asks 4/6, "How much is that? How much
do I owe?"
Well, I'm not sure. I'll have to figure it out. Why dont you take a crack at it. "OK," said the mayor. "Here goes..." The burger costs 1 and an eighth. I'm good at adding whole numbers. So I'll put the 1 here. Next I'll add the fractions. 1/2 + 1/8 + 3/4. I add up the numerators 1 + 1 + 3 equals 5. The numerators 2 + 8 + 4 add up to 14. See I told I'm good at adding natural numbers. So what I owe - drumroll please - is 1 + 5/14. 4/6 stares befuddled. What? I wouldn't give that to the wait person. Why not? Because it's WRONG! Look. If we add fraction bars you will quickly see that 5/14ths can't be right. "If you ate all that candy, how much would you eat?" asked 4/6ths. If I eat the whole bar plus 3/4 of a bar, plus another half, I'd eat more than two bars." That's right! Now you are on the right track. Now lets get the exact amount. "Well, like all citizens of Fractionville I would use a fraction calculator to find out," replied 1. "So, let's try it," replied 4/6ths. "Click on the image below." "So I owe
$19/8 which is equivalent to $2 3/8. "That's
cool. But what if I don't have a calculator
handy?" asks Mayor 1. 4/6ths suggests a
method that will work. "Notice that 1/2 and
1/8 = 4/8 + 1/8 = 5/8. So now you have 5/8 + 1
which gives you $1 and 5/8. Now we still need
to add 3/4 which can clone itself to become
6/8. So now you have 5/8 + 6/8
which is 11/8.
Since 11/8ths is improper, you need to do the proper thing and turn it into a mixed number which is 1 3/8. Almost forgot about the 1 I need to add on. So you owe $2 3/8," Mayor 1 sighs and says "There's gotta be a better way to handle this money stuff." "Ahh," says 4/6. Your wish may coming soon via another town in the woods on the other side of the mountains." "So here's 3 dollars. Keep the change as a tip," Mayor 1 says as he hands 3 crisp dollar bills to the wait person. " Otherwise I wouldn't know what to do with a "quarter.'" "Quarter?" says 4/6, "1 dollar minus 4/5ths of a dollar is not a quarter. It's 1/5 of a dollar or 20 cents." "Do you see why?" "Not sure," replied the Mayor. 4/6ths continued, "1 - 4/5 is the same as 5/5 - 4/5, because 1 and 5/5 are equivalent, because they belong to the same family. "Remember how you "shook yourself" to become 5/5 in the movie?" "That's right," said Mayor 1. "I'm the same as 5/5." Meanwhile 4/6 and Mayor 1 savored their lunch (the mayor ate his whole lunch while 4/6 ate 2/3rds) so it was time to move on. They walked out of the Fracteria and went next door to the Darts arena. |
