I just discovered a fascinating fact: In some places in the world, mixed numbers apparently don’t exist.

So that made me curious about my blog readers:

- Did you learn about mixed numbers in school?
- Do you ever use mixed numbers in daily life?
- Are your children learning to work with them?

And if you DO know mixed numbers, can you simplify this mess:

[If you enjoy dry math humor, the answer is worth the work.]

### Where These Questions Came From

Did your device hide the video? Find it on YouTube here.

“Mathematics can vary more from place to place than you might imagine.”—Adam Atkinson

I wonder if the difference between mixed-number countries and non-mixed has anything to do with when (or if) they officially adopted the metric system. Here in the U.S., I can’t imagine holiday baking without mixed numbers of cups and teaspoons.

### The Answer Is…

(In case you skipped the video.)

Isn’t it wild?

When I went to school in Finland in the 1980s, mixed numbers were definitely taught.

Thanks, Maria! I studied them in the U.S. (a couple of decades before that). I was surprised to hear that some countries ignore them.
