Question

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

Answer 1

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%

Answer 2

200 %

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 =
`(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 =
`(150)/(75)` × 100%

= 2 × 100%

= 200%

Therefore; the percentage increase is 200%
