Choose the correct proportions.

15, 6, 18, 5

a) 6:18 = 5:15
b) 6:5 = 15:18
c) 5:6 = 18:15
d) 6:5 = 18:15

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.

it would be:
