make up

[thomas615]

Are these sentences correct? I am not sure if I have used the word "missing" correctly.

I will work from 9 a.m. to 3 p.m. on Monday without my lunch. To make up the missing one hour, I will work extra an hour today and tomorrow.

I would not use "missing".
How about: I will work from 9 a.m. to 3 p.m. through lunch on Monday. To make up for the one-hour shortfall, I will work longer today and tomorrow,

I don't understand the math.
Are you missing one hour or two on Monday?
If you are working an extra hour today and tomorrow, that's two hours.

Monday I must leave at 3. I will work through lunch, and will make up the two hours by working an extra hour each today and tomorrow.

You are right. Sorry for the typo. I meant "extra half an hour" today and tomorrow. Thank you

There is nothing wrong with missing, but the "one" is unnatural. "To make up the missing hour" is natural. "To make up the missing half-hour" is also natural.
