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.
Proper Fractions. In a proper fraction, the numerator is smaller than the denominator. This holds true no matter how large both are. As long as the numerator is the smaller of the two, the fraction is a proper fraction. For example, 998/999 is a proper fraction. Even though the numbers are both large, and they're only separated by 1, the numerator is still smaller than the denominator.
