Percent

Problem:



Solution:

To solve this problem, you need to convert the fraction $ \frac{2500}{17500} $ to a percentage.

Let's start with simplifying it:

$ \frac{2500}{17500} = \frac{1}{7} $

Ooops, how do we make the denominator 100, the trick is to multiply $ \frac{100}{7} $ on both the numerator and denominator, and so we have

$ \frac{2500}{17500} = \frac{1}{7} = \frac{\frac{100}{7}}{7 \times \frac{100}{7}} = \frac{\frac{100}{7}}{100}$

Therefore the answer is $ \frac{100}{7} $ %

You can also represent that as decimal 14.29% (correct to 2 decimal place)
