What difference is there please tell me in a mathematical way​

In The first diagram, we know that its a function because each element of x has a unique face in y. That is, each element in x is joined with exactly one unique element in y. If an element from x is connected to 2 faces in y, i.e, 1 element in y connected to 2 elements in x, then it's not a function. this is what has happened in figure 2, where 1 is connected to -0 and 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.
