  2. last week she read=1/5
    this week she read=3*1/5=3/5
    she has read =last week+ this week
    =1/5 +3/5
    =4/5
    left to read=5/5-4/5
    =1/5

  5. I'm really good at this type of stuff but this one is hard. In my problem on my homework the pages in the book is 75. Since she has read 1/5 last week and 3 times that this week, we would multiply 1/5 times 3/1 to find out how many she earned that week. That equals 3/5. Then add that with the 1/5 from last week, that equals 4/5. Subtract that from 5/5, the whole amount of the book. She needs to read 1/5 of the book, which in my problem is 15. The expression should be, 5/5 - (1/5 times 3/1).
