You're running 30km? That's very impressive!
Not as easy as you thought, huh?
Don't worry, there's a water station after 3km.
That's three 30ths of the way there.
We can simplify that because both three and 30 are divisible by three.
If we divide both the numerator and the denominator by three, we can see that you'll be one tenth of the way through the race.
Hey, that's cheating!
There's another water station at 10km.
Both ten and 30 are have a common factor of ten, so if we divide both by ten, you're one third of the way.
This is definitely cheating…
But the next water station is at 18km.
18 and 30 both have a common factor of six, so if we divide both numbers by six…you're already three fifths of the way.
By the way, I didn't know you could fly a helicopter!
Simplifying fractions
You can simplify a fraction if the numerator (top number) and denominator (bottom number) can both be divided by the same number.
Six twelfths can be simplified to one half, or 1 over 2 because both numbers are divisible by 6.
6 goes into 6 once and 6 goes into 12 twice.
