we're going to think about dividing numbers

where the quotient, the result of our division,

and so you might have said something like this,

But now we don't want, we don't wanna just say,

hey, how many times can it go in and what's left over.

We wanna know exactly how many times can two go into five

so we want a decimal answer right over here.

So, pause this video and see if you can figure that out.

All right, now let's work through this together.

And there's many ways that we could approach this.

One way is to realize that five divided by two,

we could re-express as five divided by two

or as five halves and five halves is the same thing

which is the same thing as four halves plus one half

which is the same thing as four halves is two.

and if we were to express that as a decimal

So five divided by two, you could say, 2.5.

Now another way that you could approach this is you say,

well that's going to result in 25 of the something.

So this is going to be equal to 25 tenths.

And how would we express 25 tenths as a decimal?

and then 20 tenths is the same thing as two ones.
