Algebraic fractions in this problem set look like 33x³/(11x) which simplifies to 3x². When fractions are in the "most simplified form" the numerator and denominator show the lowest possible number and all variables have the lowest possible exponents.
45x³/(9x) = 5x²
45x/(9x) = 5
45x³/9 = 5x³
For each problem in this problem set observe the fraction carefully and "simplify completely". Strive to be able to simplify with ease and then strive for increasing your speed. Good luck and enjoy the challenge!
