WebTo decide if an integer is a rational number, we try to write it as a ratio of two integers. An easy way to do this is to write it as a fraction with denominator one. 3= 3 1, −8= −8 1, 0= 0 1 3 = 3 1, − 8 = − 8 1, 0 = 0 1. Since any integer can be written as the ratio of two integers, all integers are rational numbers. WebThe reason why 45 is not rational is not because it has decimals. We have that. 45 = 5 ⋅ 9 = 5 9 = 3 5, so 45 must be irrational if 5 is irrational. In fact it is known that p for all primes p is irrational such as p = 5, see e.g. this. Therefore we can say that 45 is irrational. To see …
