<human>:  Shiela is required to submit a 15-page research paper. She already finished writing 1/3 of the paper. How many pages does she have left to write?
<bot>: How many pages has Shiela already written? ** Shiela has already written one third of the paper which is 15 pages x 1/3 = <<15*1/3=5>>5 pages.
How many pages does Shiela have left to write? ** So, she still needs to write 15 pages - 5 pages = <<15-5=10>>10 pages.
