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.
Ratio of Two Numbers. We assume that you are familiar with arithmetic operations on integers, and are able to find the Lowest Common Multiple (LCM) of numbers. We are interested in numbers that can be written as a quotient of two integers: (a,b integers, b0) Such a quotient is called a fractional number or just a fraction. Here are some examples: , , , , , The top part of a fraction is called the numerator and the bottom part the denominator of the fraction. Note that any integer b can be written as the ratio of two numbers. Namely .
