Well lets start by narrowing the answers. You can't have a fraction as a irrational number so even though 4/3= 1 1/2 its still not an irrational number. Negative 4.07 also can't be an irrational number because an irrational number is a number that never ends and even thought irrational numbers can be written as decimals -4.07 is not an irrational number. I don't really want to give u the answer but I did limit ur choices so hope that helps!!!
