The bacterial numbers from whirlpool bathtubs were not significantly different. based on the tub location (private 1.65 x 10 6cfu/ml and hotel 2.64x 10 cfu/ml, p=0.22). Normal (nonjetted) tub water. samples (1210 cfu/ml) were not significantly different from tap water samples, (p=0.99).
A simple fraction (also known as a common fraction or vulgar fraction) is a rational number written as a/b or a b {\displaystyle {\tfrac {a}{b}}} , where a and b are both integers. As with other fractions, the denominator (b) cannot be zero.
Rational expressions, or fractions containing polynomials, can be simplified much like fractions can be simplified. To simplify a rational expression, first determine common factors of the numerator and denominator, and then remove them by rewriting them as expressions equal to 1.ational expressions, or fractions containing polynomials, can be simplified much like fractions can be simplified.
