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.
Normally expressing fractions one says the number divided by the number dividing (dividend by quotient) thus two thirds, three quarters, five sixteenths. In these cases the dividend is more than 1. If The dividend is 1 then one would say a half or one half, a fifth or one fifth.
