4 hours

Ricky is building 7 shelves for his office. It takes 30 mins to build each shelf so 30×7 =3 hours and 30 mins.

I know this is a bit fast, but we make it up, don’t we?

Ricky is building 3 shelves for the office. It takes 10 mins to build each shelf. He’ll be done building the sets in 2/4 hours.

I used 2/4 because I already used the number 1.

Ricky is building 4 shelves. each shelf takes 30 min. he will be done in 1 hr
