Determining the scaling factor:

Applying a scaling factor to convert fractions to percentages:

Solution:

For fractions:

In this guide, we’ll be focusing on the fraction 9/30 and how to convert it into its percentage equivalent.

Method 1 – Fraction Scaling:

1. Understanding Fractions: At the heart of every fraction, there's a division taking place. The numerator denotes the 'portions' we're focused on. The denominator reveals the total possible 'portions'. So, when we say $\frac{9}{30}$, we're essentially talking about 9 'portions' out of an available 30.
2. Explanation of Percentage: The term “Percent” has Latin roots, where “cent” means a hundred. So, a percentage essentially portrays a fraction where the denominator is always 100. For illustration, when we state 50%, it translates to 50 out of 100 or $\frac{50}{100}$ in fraction terms.
3. Transformation Process: To convert $\frac{9}{30}$ into a percentage, we must multiply the fraction to have 100 as its denominator. Begin by determining the factor by which 30 can be multiplied to get 100. This factor is $\frac{100}{30}\mathrm{=\; 3.3333333333333}$. Following this logic, multiply both the numerator and denominator by 3.3333333333333:$\frac{\mathrm{9\; \times \; 3.3333333333333}}{\mathrm{30\; \times \; 3.3333333333333}}\mathrm{=}\frac{30}{100}$.
4. Final Step: Once multiplied, the fraction denotes 30 out of 100, which is equivalent 30%.

Method 2 – Using Decimals:

1. Fraction to Decimal Transformation: Begin by expressing $\frac{9}{30}$ as a decimal. This step requires simple division: divide the numerator (9) by the denominator (30), resulting in 0.3.
2. Decimal to Percentage Conversion: Now, transform this decimal into a percentage. So, 0.3 multiplied by 100 equals 30%.
3. Wrapping Up: Through the decimal conversion method as well, $\frac{9}{30}$ is equivalent of 30% when expressed as a percentage.

Both methods, while distinct in approach, provide the same result. You can choose to use either the direct fraction scaling method or the decimal conversion method.
