Answer:


(1)/(3)

Explanation:

I'll assume it is
(21)/(6)÷
(21)/(2)

Not so sure if it is that or in mixed form

The division sign will become multiplication sign when two becomes the numerator and 21 becomes the denominator


(21)/(6)×
(2)/(21)

21 will cancel out leaving
(2)/(6)

=
(1)/(3)

Answer:

Change the mixed numbers into an improper fraction:


2\frac16 / 2\frac12=(2 * 6+1)/(6)/ (2 * 2+1)/(2)=(13)/(6)/ (5)/(2)

Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. (Reciprocal is when you swap the numerator and denominator). Therefore,


(13)/(6)/ (5)/(2)=(13)/(6)*(2)/(5)

Now we simply multiply the numerators and the denominators:


(13)/(6)*(2)/(5)=(13 * 2)/(6* 5)=(26)/(30)

We can now reduce the fraction to its simplest form by dividing the numerator and denominator by 2:


(26)/(30)=(26/ 2)/(30 / 2)=(13)/(15)
