-3.5,-3,-v3,1,0,2/9,v5,15.3,18 my teacher said to write which ones are natural, rational, whole, integers, irrational, & real which i understand but i don't know what she means by -v3 & v5?
I am taking a wild guess that what you wrote as
v5 was really √5
numbers such as √5 and -√3 are irrational, since they cannot be written as fractions, where numerator and denominator are integers
irrational ----> not rational ----> not a ratio
