So guess what? Fractions are just the same thing as division... That one made us question reality for a few weeks.
|Elementary and Middle School||5th Grade|
And sure, that might make fractions seem puny and unimportant, like they're just leftovers. [sad fraction leftovers]
Which… hey, we love leftovers.
No complaints here.
However, it turns out there's a lot going on in a fraction. [numbers fly by]
You might have noticed that all fractions have a little line in their middle, like they're
wearing a little belt. [adorable fraction belts]
That lil' belt is called the fraction bar. [fraction bar labelled]
And it's not just there to look stylish, even though fraction bars are definitely slimming. [runway fraction]
It turns out the fraction bar is actually a division sign in disguise. [bar turns into division sign]
Every fraction has a numerator above the fraction bar…
…and a denominator down below. [fraction diagram]
And even though it's fine and dandy to leave a fraction as a fraction, we can also transform
it into a division. [Coop illustrates concept]
We just take our numerator…
…and divide it by the denominator. [fraction division shown]
Plus, if you actually want to carry out the division, you'll get a decimal number, free
of charge. [person celebrates decimals]
Fractions…they really are the gift that keeps on giving. [person opens disappointing gift]
Oh, and pro-tip: never give fractions as presents.
They're the number two most re-gifted gift, right after candles.
Anyway…it kinda makes sense that we should be able to translate from fractions to decimals. [fraction turns into decimal]
Sure, we don't often talk about having "0.125 of a pizza," but decimals are still a handy
tool for representing parts of wholes… [pizza man is confused]
…and the fraction bar provides a great bridge from fractions to decimals.
Luckily for you, writing a fraction bar only requires you to draw a tiny horizontal line… [person draws fraction]
…rather than making an actual bridge.
It'd be a real pain if you needed a few tons of steel and concrete every time you wanted [bridge building videos]
to make a fraction.
So there ya have it.
Thanks to the fraction bar, fractions aren't a bunch of puny nobodies, but the ambassadors [fractions guard world of decimals]
to the world of decimal numbers.
Now if you'd excuse us, we've got an eighth of a pizza to finish off. [person eats pizza]
