Basic concept: A/B = C/D process is called cross-multiply and solve for the unknow. In this case, like your's let's solve for B Step 1: (multiply the numerator of one fraction to the denominator of the other fraction on the other side of the equal sign)...so B x C Step...

April...simpliest way is to substitute the proposed answers... 9 or 5 into the original equation and do the operation. You will see which one is correct...then you will be the MASTER

The rule that allows for the inversion of the negative exponents is: x^-n = 1/x^n or 1/x^-n = x^n that is how we can rewrite the equation as s^-3t^-5/(s^2t^3)^-1 = [(s^2)(t^3)]^1 / [(s^3)(t^5)] with the ^ it can get a bit confusing...but rewrite the equations...

Yessica...hello from ABQ I understand your problem 2-x/1-x/2 to be ( 2 - x )/( 1 - x/2) In words, the quantity 2 minus 2 divided by the quantity 1 minus x over 2... correct? When these responses get sent, then don't always look like we are invisioning them...so I'll use words as well...
