I can answer questions in basic algebra and any grade school math.
Love math, currently helping my nephew get through Intermediate Algebra.
I majored in Math Ed in college (but decided not to teach), so have over 40 credits of math.

divide both sides by 9000 and reduce 5/9 = (1 + r)^10 Take the 10 root of both sides. Not sure how to write that here, but it's the square root symbol with "10" in the angled part in front. 10th
Because you're starting with 2 different numbers. In one case you're dividing 4 into parts and in the other, you're dividing 5. You're ultimately asking why 4/5 does not equal 5/4 and I don't know how
As you have it (1/7)/ 15 X 21, then 1/5 is the correct answer. Remember PEMDAS, which stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction P Parentheses first
Ok, the only reason your "reduction" works is because you've already multiplied the 1/21 and 15 and you're reducing a fraction. We are saying the same thing. I say the easiest way to solve is to divide
Not sure what you're doing with your calculations, but you can't just "reduce" (ie divide by 3), 2 elements of the equation and not the third. The easiest way to figure out how many days it would take
