If we multiply 3.14 by 100 the decimal point will move two places to the right, i.e.
- \displaystyle 100\cdot 3{,}14 = 314
and dividing both sides by 100 we see
- \displaystyle 3{,}14 = \frac{314}{100}\,\mbox{.}
This shows that 3.14 can be written as the quotient of two integers which means it is a rational number.
