How do I get better at doing questions with prevents and numbers that are bigger then 100 like an example would be 37% of 280. How do i study this?
You could "estimate", and then do lots and lots of practice : )
If you estimate... you could use "friendly" numbers. So 37% could be "nice and friendly" at 50% and 280 would become 300. So your answer would be less than 150, and... if you use 25% that would be half of your 150 or 75. So your answer "using friendly" numbers is between 75 and 150 : ) And since 37% is part way between 25 and 50, your answer would be pretty much exactly halfway between 75 and 150, that is 100.
That way, when you practice, practice, practice you know a great estimate to your question.

Math tutors may have more ideas for you.
The word “of” usually means you need to multiply.
37% needs to be converted to .37 before using it in a math problem.

Click on Courses and choose what you need. Or search for what you want help in — I searched for ‘percentages’ and several good webpages showed up.
Thank you!
To become better at doing percentage questions involving larger numbers, like finding 37% of 280, you can follow these steps to study and practice:
1. Understand the concept of percentages: Start by having a clear understanding of what percentages represent. A percentage is a way of expressing a fraction or a portion of a whole out of 100.
2. Learn the percentage formula: The percentage formula is helpful for solving problems involving percentages. It is: Percentage = (Part/Whole) x 100. This formula allows you to find a percentage by dividing the part you are interested in by the whole, then multiplying by 100.
3. Familiarize yourself with basic percentage values: Memorize and practice common percentage values, such as 1%, 5%, 10%, 25%, 50%, and 75%. This will help you quickly estimate percentages and compute them mentally.
4. Practice mental calculations: Work on developing your mental math skills to perform quick calculations involving percentages. This will enable you to estimate and solve problems more efficiently.
5. Solve practice problems: Start with simple percentage problems and gradually progress to more complex ones. Begin by finding percentages of smaller numbers and then move on to larger numbers. Use textbooks, online resources, or worksheets to find a variety of practice problems to solve.
6. Analyze solutions and errors: After solving each problem, carefully analyze your solution. Identify any mistakes made and understand why they happened. This will help you correct errors and improve your understanding.
7. Review and repetition: Regularly review the concepts and formulas associated with percentages. Practice regularly to reinforce your knowledge and increase your speed.
8. Use real-life examples: Look for real-life examples where percentages are used, such as discounts, interest rates, or statistical data. This will make the concepts more relatable and increase your understanding.
By following these steps, you can gradually improve your skills in solving percentage problems involving larger numbers. Remember that consistent practice, understanding the concepts, and analyzing your solutions are key to enhancing your abilities.
