I was going to do it that way, but I thought it had to be done by that formula (r*b=a). Are they any sites to help me with this. The last thing i want is to be confused. Thank you.

I don't know of any formula or sites that can help you.

Does my answer and procedure make sense to you?

yes ma'am and thank you again.

Yes, there are several websites that can help you with understanding and solving equations. One useful website is Khan Academy (www.khanacademy.org), which offers a wide range of math tutorials, exercises, and videos. They have a specific section on algebra, where you can find lessons on solving equations, including the formula you mentioned (r * b = a).

Another great website is Wolfram Alpha (www.wolframalpha.com), which is a computational knowledge engine. It can not only solve equations but also provide step-by-step solutions, which can be very helpful for understanding the process.

If you prefer a more interactive approach, you can try online math forums such as MathHelpForum (www.mathhelpforum.com) or Math Stack Exchange (math.stackexchange.com). These platforms allow you to ask questions and receive answers from other users who are knowledgeable in mathematics.

Remember, it's always important to understand the underlying concepts and principles rather than relying solely on formulas. Exploring these websites can provide you with additional resources, explanations, and examples to help deepen your understanding of equations.
