Understanding how to convert fractions to decimals is a foundational skill that can greatly simplify the process of working with numbers. To start, a fraction represents a part of a whole and is composed of two parts: a numerator, which is the top number, indicating the parts being considered, and a denominator, which is the bottom number, indicating the total number of equal parts in the whole.

Conversion from a fraction to a decimal is straightforward. You divide the numerator by the denominator. For example, with the fraction \(\frac{7}{8}\), you would perform the division 7 ÷ 8. This division yields the decimal 0.875. It's essential to carry out the division accurately to ensure the decimal result is correct, as the subsequent step involves turning this decimal into a percentage.

Once you have a decimal, transforming it into a percent is simple and involves a basic understanding of what percentages represent. A percentage is a way of expressing a number as a fraction of 100. Therefore, converting a decimal to a percent is as simple as multiplying the decimal by 100.

For our example, take the decimal 0.875. To find the percent, we calculate \(0.875 \times 100\). This calculation gives us 87.5, which means that \(\frac{7}{8}\) is equivalent to 87.5%. Remember to always include the percent sign after the number to indicate that the value is a percentage. This step is a crucial part of percent notation, indicating that the number is a hundredth of a whole.

Percent notation is a succinct way to represent comparisons and ratios. The percent symbol \(\%\) is a visual indicator that the number preceding it should be understood as a fraction of 100. The term 'percent' itself comes from the Latin 'per centum', which translates to 'by the hundred'.

To illustrate, when we say 50%, we mean 50 out of every 100 or 50/100, which simplifies to the fraction 1/2 or the decimal 0.5. Percent notation is widely used in many areas such as finance, statistics, and probability because it is a universally recognized way to express proportions and probabilities in a clear, concise manner.
