    A test has 40 questions. Denise finished ##2/5## of the questions in the first 10 minutes and ##1/2## of the remaining questions in the next 15 minutes. How many questions had Denise answered after 25 minutes?

    Denise had answered ##28## questions after ##25## minutes.

    The first step is to see what ##2/5## of ##40## is

    ##2/5 * 40=16##.

    Then, we can subtract this number from ##40##

    ##40-16 = 24##

    Now, we can see what half of ##24## is. This is ##12##.

    Finally, we add

    ##12+16= 28##

    Hope this helps!
