Nick spent 1 3/4 hour doing homework. of that time, 2/3 was spent on social studies project. how many hours did Nick spend working on his project?

Ok so this would mean that nick used 2/3 of that time to do his homework and the rest of the time to work on his project. That would mean you would have to do 1 & 3/4 subtract 2/3 then you would have your answer.
