Let's see if we can write twelve point nine eight as a mixed number.

So, the first thing you might want to realize here is that this is the exact same thing

as twelve plus zero point nine eight.

And this simplifies it, because then we just have to write it as twelve and some fraction that's the same

thing as zero point nine eight. So, if we can write zero point nine eight as a fraction

then we can, we're essentially, we're almost done!

So let's see if we can do that.

So, this nine right over here is in the tenths place.

I'll just write it like that. Tenths place. And this right over here is in the hundredths place.

It's in the hundredths place. So you can view zero point nine eight two different ways.

You can view it as nine tenths. Nine tenths.

That's this part over here, nine tenths plus plus eight hundredths, plus eight hundredths.

And if you want to find a common denominator that would be the same thing as ninety over one hundred

plus eight over one hundred. Plus eight over one hundred, which is equal to ninetyeight over one hundred.

Equal to ninetyeight over one hundred. And so, zero point nine eight is ninetyeight hundredths.

And another way you could have said that is, "Look, this space over here is in the hundredths place. And so this is ninetyeight hundreds, or ninetyeight hundredths."

So, you could have skipped this right over here. So, if we wanted to write this as a mixed number,

we could just write it as twelve and, instead of zero point nine eight, twelve and ninetyeight hundredths.

Now, we haven't reduced this to lowest terms. So, let's se if we can simplify this.

Ninetyeight is divisible by two, and so is a hundred. So, lets divide both of them

by two. They have that common factor. So, we can divide both of them by two.

And so, this is the same thing as twelve and ninetyeight divided by two is nine is fortynine.

A hundred divided by two is fifty. And I think that's about as far as we can do.

Fortynine's factors, it's divisible by seven, but fifty isn't.

So we've put it in lowest terms. So, twelve point nine eight can be written as a mixed number,

twelve and fortynine fiftieths.
