Question

From 75 pencil to 225 pencils. Round to the nearest percent.

Answer 1

Answer:

200 %

Step-by-step explanation:

From the question above, the pencils increases from 75 to 225, so  what we are looking for is the percentage increase

The formula for finding percentage increase is;

% increase =    $\frac{Increase}{Original}$       ×   100%

First; we will find the difference between the two numbers i.e 75 and 225

Increase = New number - Original number

                         = 225      -   75

                          =  150

Then we divide the increase by the original number and then multiply by 100 %

That is;

% increase = $\frac{150}{75}$   ×  100%

                   = 2   ×  100%

 

                     = 200%

Therefore; the percentage increase is 200%

Answer 2

For finding percents, I use a method called FOO
which is final-original÷original
the original is the first number and the final is the second
After FOO you must multiply by 100 to make it a percent
The equation is as followed:
225-75÷75×100
The answer is 125%
