Once you press this button, the calculator will display the decimal equivalent of $\frac{6}{65}$, which is approximately 0.0923. Converting the fraction to a decimal is a crucial step in finding the percentage. The ALEKS calculator performs this conversion accurately and quickly. The decimal representation gives a clearer picture of the fraction's value, making it easier to convert to a percentage. It's important to understand that the decimal is a bridge between the fraction and the percentage. The accuracy of the decimal conversion is paramount for an accurate final percentage. If you were to perform this conversion manually, you would divide the numerator by the denominator. The calculator automates this process, eliminating the need for long division. Always make sure that the calculator is in the correct mode for decimal conversion to avoid any unexpected results. Practice with different fractions to reinforce your understanding of this step.

Step 3: Convert to Percentage

To convert the decimal to a percentage, multiply the decimal by 100. On the ALEKS calculator, this usually involves entering “x 100” after the decimal value. The result will be 9.23%. To convert to percentage, you multiply the decimal by 100. This step is based on the definition of percentage, which means “out of 100.” Multiplying by 100 effectively scales the decimal value to a percentage. The ALEKS calculator performs this multiplication effortlessly, providing the percentage value directly. Understanding why this multiplication works is crucial for grasping the concept of percentage. It’s not just about following a mechanical step; it’s about understanding the relationship between decimals and percentages. If you were to perform this step manually, you would simply move the decimal point two places to the right. The calculator does this instantly. Make sure to include the percentage symbol (%) in your final answer to indicate that it is a percentage. This step is the final transformation, converting the decimal representation into a readily understandable percentage.

Step 4: Round to the Nearest Tenth

The final step is to round the percentage to the nearest tenth. In this case, 9.23% rounded to the nearest tenth is 9.2%. Ensure you round correctly based on the hundredths digit. Rounding to the nearest tenth means looking at the digit in the hundredths place. If it is 5 or greater, you round up the tenths digit; if it is less than 5, you leave the tenths digit as it is. In this case, the hundredths digit is 3, which is less than 5, so we round down to 9.2%. Rounding is an essential skill in mathematics, ensuring that your answers are precise and meaningful in practical contexts. The ALEKS calculator provides the value to several decimal places, but rounding makes the answer more concise and easier to interpret. Practice rounding with different numbers to improve your proficiency. This final step ensures that the answer is presented in the requested format, providing a clear and accurate result.

Common Mistakes and How to Avoid Them

Make sure you are using the correct keys for fractions and not accidentally entering decimals or whole numbers. Practice entering fractions carefully to minimize errors. Using the clear button to start fresh if you suspect a mistake is a good habit. Accurate input is the foundation of the entire calculation, so this step deserves extra attention.

Forgetting to Multiply by 100

Another common error is forgetting to multiply the decimal by 100 to convert it to a percentage. Remember that a percentage is a number expressed as a fraction of 100, so this multiplication is essential. A helpful way to remember this step is to write it down or make a mental note before converting the fraction to a decimal. The multiplication by 100 shifts the decimal point two places to the right, transforming the decimal into a percentage. Skipping this step will result in the decimal value being presented instead of the percentage, which is incorrect. Always double-check that you have completed this step before finalizing your answer. Reinforce this step by understanding the concept behind it: a percentage is a proportion out of one hundred.

Rounding Errors

Rounding errors can also lead to incorrect answers. Ensure you are rounding to the correct decimal place as specified in the instructions. In this case, we needed to round to the nearest tenth of a percent. Review the rules for rounding if you are unsure. If the digit to the right of the rounding place is 5 or greater, round up; if it is less than 5, round down. Rounding should be the final step in your calculation to avoid compounding errors. Practice rounding with different numbers to become more comfortable with this process. Make a habit of checking the instructions to confirm the required rounding precision. Understanding the rules of rounding and applying them consistently will help you avoid these errors.
