    First, make the fraction a common denominator.
    1/8 becomes 3/24
    1/3 becomes 8/24
    1/4 becomes 6/24
    Reading a whole book is equal to 1 so you can subtract what you already read to see what Justin read on the fourth day.
    1 can also be written as 24/24.
    24/24-3/24-8/24-6/24=7/24
    So, Justin read 7/24 of the book on the fourth day.

    Hope this helped! 🙂

    What part of the book did Justin read on the fourth day ?

    8/8 – 1/8 – 1/3 – 1/4 =

    = 24/24 – 3/24 – 8/24 – 6/24

    = (24 – 3 – 8 – 6)/24

    = 7/24
