Question

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. StartFraction part Over whole EndFraction = StartFraction 60 Over 100 EndFraction Step 2: Write an equivalent ratio that has the answer in the numerator and 20 in the denominator. Step 3: 100 divided by 20 = 5 Step 4: 60(5) = 180 What mistake did Kato make?

Step 1: Write 60 percent as a ratio. StartFraction part Over whole EndFraction = StartFraction 60 Over 100 EndFraction
Step 2: Write an equivalent ratio that has the answer in the numerator and 20 in the denominator.
Step 3: 100 divided by 20 = 5
Step 4: 60(5) = 180

What mistake did Kato make?
In Step 1, Kato should have written the ratio as StartFraction 100 Over 60 EndFraction.
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.

Answer 1

Answer:

Kato must write 12 pages of the report

Step-by-step explanation:

We have given that total number of pages in report = 20

It is given that Kato must write 60 % of the that report tomorrow

We have to find the number of pages which kato write tomorrow

So number of pages which kato write tomorrow =\frac{20\times 60}{100}=12=

100

20×60

=12

So kato must write write 12 pages of the report tomorrow because 60 % of 20 is 12
