The prevalence of thyroid cancer has been shown to be similar in patients with a solitary nodule and patients with multiple nodules [30]. In glands with multiple nodules, the recommendation of the American Thyroid Association (ATA) is to biopsy nodules that are >10 mm and those that have suspicious features [15].
Rational Numbers: Any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. An integer can be written as a fraction simply by giving it a denominator of one, so any integer is a rational number.
Pi is an irrational number. A rational number is one that can be expressed as a fraction (or ratio), e.g. 1/3. There are fractions that are near Pi, for example: 22/7 = â¦3.142857 (PI = 3.14159265...) A closer fraction is: 355/113 = 3.14159292 However whatever fraction you have, you will never get exactly PI.
