Step-by-step explanation:

In order to solve this question, we must divide 321 by 12, since there are 321 visitors, and each table seats 12 people.

321 ÷ 12 = 27 when rounded to the nearest whole number.

Therefore, 27 tables are needed to seat all of the visitors.

step-by-step explanation:

it's is b

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.
