Question

Are both 7 and -1/2 rational numbers? Why or why not?

Answer 1

according to the definition of rational number a number which can be written in the form of p upon q where Q is not equal to zero and P and Q both are integers.

so 7 can be written as 7/1
where 7 and 1 both are integers

and in -1/2
both the numbers are integers

so we can say that both are rational numbers
