What is an irrational number means?
a number that cannot be expressed as a fraction or a ratio. Formally, we say a number is rational if it can be written in the form p/q where p and q are integers. If it cannot be written this way, it is irrational.
How would you convince a fellow student that the number 0.57 is a rational number?
0.57 can be written as 57/100. 57 and 100 are both integers and therefore 0.57 can be written as a ratio of 2 integers. A number that can be written as a ratio of two integers is a rational number because the word rational comes from ratio.
