Question

What does 5 over 100 =

Answer 1

You can identify that "5 over 100" can be written as a fraction. 5 will be the numerator and 100 will be the denominator:

$\frac{5}{100}$

To reduce this fraction, you need to divide the numerator and the denominator by the Greatest Common Factor (GCF) between them.

In this case, to find the GCF, you need to:

- Decompose the number into their Prime Factors:

$\begin{gathered} 5=5 \\ 100=2\cdot2\cdot5\cdot5=2^2\cdot5^2 \end{gathered}$

- Notice that 5 is a common factor. Then, you need to choose the one with the lowest exponent:

$GCF=5$

Therefore, by dividing the numerator and the denominator by 5, you get:

$=\frac{1}{20}$

Hence, the answer is:

$=\frac{1}{20}$
