We've practiced matching words and full numbers together. Let's do a little more of this. It takes time and exposure to feel comfortable reading long numbers. It won't feel perfect even after a little more practice, but that's okay! We have tools that can keep helping us when we see a number we're less familiar with.

a$)$ Let's convert $4\mathrm{.}5E+8$ into both it's full number and write it with words:

As a full number, $4\mathrm{.}5E+8$ would be written like this:

Enter an integer or decimal number $[$more$.]$

In words, we'd most likely write $4\mathrm{.}5E+8$ like this:

Select an answer $vv$

b$)$ Now we'll convert $19\mathrm{.}56$ billion into scientific notation and it's full number versions:

We'd write $19\mathrm{.}56$ billion in scientific notation like this: $$

$E+$

The full number for $19\mathrm{.}56$ billion is written like this:

c$)$ One more. We'll convert $245,000$ into scientific notation and written with words $($granted$,$ this number isn't so long that a calculator would ever give in scientific notation, but let's try it anyways$).$

The scientific notation for $245,000$ would be $$ E$+$

In words, we'd write $245,000$ as $$ Select an answer $vv$
