Question

Darius lifted weights for 15 minutes a day, every day, for the month of January. How many hours did he lift weights in January?

Answer 1

`7.75` hours

Explanation:

If there are 31 days in January, then:

`(15 cancel(" min"))/(1 cancel(" day")) * (31 cancel(" days"))/" January" * (1 " hour")/(60 cancel(" min"))=7.75` hours in January

All of the fractions after the initial one are equal to one, and simply change your "unit" until you get the one you want, which is hours in January.
