    1/3 of 60 minutes is 20 minutes so she spend 20 minutes texting

    1/4 of 60 minutes is 15 so she spent 15 minutes brushing her teeth and putting on pajamas

    that is 35 minutes total so far, so you need to subtract 35 from 60 to get a final answer of 25

    1 hour = 60 minutes

    1/3 of an hour is 20 minutes

    1/4 of an our is 15 minutes

    so she spent 20 minutes + 15 minutes doing other stuff

    60minutes - 35 minutes means she has 25 minutes left to read
