There is at least one example:
4/5 = 0.8
5/4 = 1.25
Because they are terminating decimals
When expressed as a decimal, a rational number will either be terminating (end with a finite number of digits) or repeating (have a repeating pattern of digits).
terminating decimals repeating decimals
Some can. For example, 1/3 = 0.3333.... recurring.
Decimals can be recurring. Decimals can be terminating. They can't be both.
The former can be expressed as a fraction whereas the latter can't be expressed as a fraction.
Because they are terminating decimals
Any number that can be expressed as a fraction can also be expressed as a terminating decimal and a non terminating decimal can't be expressed as a fraction and so therefore it is an irrational number.
Any number that can be expressed as a fraction can also be expressed as a terminating decimal and a non terminating decimal can't be expressed as a fraction and so therefore it is an irrational number.
irrational numbers
fractions or decimals
Terminating decimals are decimals that end, such as, 2.384. Non-terminating decimals that don't end, such as, 0.3333333333.......
When expressed as a decimal, a rational number will either be terminating (end with a finite number of digits) or repeating (have a repeating pattern of digits).
No. Rational numbers are either terminating decimals or non-terminating BUT recurrent decimals.
