Jan has 500 pages of paper.
She has a report of 16 pages.
But a report is printed on both sides of the page.
So the complete report shall be printed on 8 pages.
Now as the total pages are 500
We shall divide 500 by 8 and convert the simplified fraction to mixed no.
Now
So we shall be able to print 62 complete copies of the report which shall use 62 × 8 = 496 pages.
Number of pages left = 500 - 496 = 4 pages.
