Kato must write 60 percent of a 20-page report by tomorrow. Kato wants to determine the number of pages that he needs to write by tomorrow. Kato’s work is shown below.

Step 1: Write 60 percent as a ratio. part/whole = 60/100

In Step 2, Kato should have put 20 in the numerator.
In Step 3, Kato should have multiplied 100 by 5.
In Step 4, Kato should have divided 60 by 5.
