You can buy 3 t-shirts for $24. write a proportion that gives the cost c of buying 7 t-shirts.

$56

Step-by-step explanation:

Divide 24 by 3 to get 8

$8 will be the amount it'll cost for 1 t-shirt

So you would multiply 7 by 8 to get 56

So $56 will be the amount of 7 t-shirts

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.
