Bei Qian Rational and irrational numbers Are Real Numbers used in real life? Real Numbers Conclusion Real numbers are vital for everyday life. We use them for quantities such as age, price, size, or population. Real numbers are numbers that exist on a number line, and can be expressed, regardless if they are rational, or irrational. A rational number is a number that can be written as a simple fraction

Example:

2.5 is a rational number because 2.5 = 5/2 (can be written as a fraction)

An Irrational Number is a real number that cannot be written as a simple fraction.It cannot be written as a ratio of two integers...

Example:π (pi) is an irrational numberπ=3.1415897932384626433832795…(unable to write down a simple fraction that is equals to π)

The popular approximation of 22/7 = 3.1428571428571... (It is close but is not accurate) Real numbers are used in our daily lives for even the simplest things like paying the bus fare, sharing food or walking.
