Than vs that

Could you please take a look at this?

There is an extra than but no comparative form. How would you phrase the following?

1 / I make more than you in 2 day than you do in 5 days.

2 / In 2 days I make more than you do in 5 day.

Would you use that or than? Is the sentence grammatical?

In 2 days I sleep more than half the amount that/than I sleep in 5 days during the week.

I sleep more than half the amount in 2 days that/than I do in 5 days.

I know this is correct but are 2 and 3 correct?

1 / I get about half as much sleep over the weekend as I do the other five days of the week put together.

2 / I get a little more than half as much sleep over the weekend as I do the other five days of the week put together.

3 / I get a little more than 2 times as much sleep over the weekend as I do the other five days of the week put together.

thank you!!
