<p class="pro-note">💡 Pro Tip: When finding percentages of non-whole numbers, ensure your calculator or math method accounts for decimal points accurately.</p>

Troubleshooting Percentage Calculations

• Double-Checking: Use the reverse method to check your calculations; if 30% of 35 is 10.5, then 10.5 divided by 35 should yield 0.30.
• Alternative Methods: If you're unsure, use different approaches like the proportion method:
  • Set up a proportion where the part is to the whole as the percentage is to 100.
    • 10.5/35 = 30/100, which simplifies to 10.5/35 = 3/10, confirming the accuracy.
