Midbrain. The midbrain, also called the mesencephalon, is a small region of the brain that serves as a relay center for visual, auditory, and motor system information. It regulates autonomic functions, those that the body carries out without conscious thought, such as digestion, heart rate, and breathing rate.
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.
That is it has an infinite decimal places as the value of pi is no finite. Since the pi is an infinite number (after decimal) or the value after the decimal is non â terminating (that means the value has no end), therefore the number 3.14159265 cannot be displayed as a ratio of two integers.et us remind the concept of Rational Numbers. Rational numbers are the Ratio of two different unified integers. Or in other words, we can say that rational numbers are simply the ratio of two numbers with no common factor in them.
