Is 3.14 an irrational number a rational number or an integer?
3.14 is rational. However, it is often used as an approximation for pi, which is irrational.
How can you use integers to reprsent the speed and velocity of an object?
You can sometime use integers but often speed or velocity can also be irrational.
What fraction is the equivalent of pi?
pi is irrational so there can be no fraction that is equivalent. 22/7 is often used as a simple approximation.
What number does the Pi symbol stand for?
An irrational number representing the ratio of the circumference of a circle to its diameter. 22/7 (3.142857) is often used as a close representation, 355/113 is closer at 3.141529.
How are rational numbers different than irrational numbers?
Rational NumbersA rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1.Likewise, 3/4 is a rational number because it can be written as a fraction.Even a big, clunky fraction like 7,324,908/56,003,492 is rational, simply because it can be written as a fraction.Every whole number is a rational number, because any whole number can be written as a fraction. For example, 4 can be written as 4/1, 65 can be written as 65/1, and 3,867 can be written as 3,867/1.Irrational NumbersAll numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point. Here are some irrational numbers:π = 3.141592… = 1.414213…Although irrational numbers are not often used in daily life, they do exist on the number line. In fact, between 0 and 1 on the number line, there are an infinite number of irrational numbers!
