12. \( 90 \% \) of 300

To find \( 90\% \) of 300, simply multiply 300 by 0.90 (because \( 90\% \) in decimal form is \( 0.90 \)). So, \( 300 \times 0.90 = 270 \). Therefore, \( 90\% \) of 300 is 270! Additionally, using percentages is a handy skill in daily life! For example, when shopping, knowing how to calculate discounts can help you snag sweet deals. If something costs $300 and is discounted by \( 10\% \), you can find out you're saving $30, making it just $270. How cool is that? Finally, if you're diving deeper into percentages, calculators or even spreadsheet software like Excel can quickly compute these figures for you. But remember, practicing mental math with percentages can sharpen your skills and impress your friends! Keep at it!
