I'm procrastinating doing my paper. But I'm going to tell you something fun about math, so... I mean, I'm kinda doing mathy-stuff, ok?
So if you have a fraction in lowest terms, (like 1/8 instead of 2/16)
with a denominator (bottom number) that is a prime factorization of 2 or 5 or any combination of 2 and 5,
(the prime factors of 8 are 2 x 2 x 2 which is 2 cubed or 2^3)
then you automatically know that when the fraction is turned into a decimal that it will terminate (not repeat or go on forever).
You also know how many places after the decimal it will end because it will be the higher power or 2 or 5.
In the case of 1/8, we only have 2 with a power of 3 and the decimal terminates after 3 places at 0.125.
How cool is that?! 😲😲😲
There is more, but I'll save it for another day if anyone even cares about this. 😆
If you're up for it test this out by making fractions with denominators from multiples of 2 or 5 or any combination of 2 and 5 and see if you can come up with one that doesn't work. 😁 Don't forget that the fraction has to be reduced to lowest terms!
