number?

2, 3, 5, 7, and 11.

Step-by-step explanation:

THose are 5 of the most common prime numbers so what ever 3 to the power of 6 is. would not be on the list.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
