Step-by-step explanation:

21yz

--------------

49xyz

We can break this into pieces

21   1        y          z

--- * ---- * ----- *   ----

49    x      y          z

Now we can simplify. canceling the y terms and the z terms

3*7   1         1          1

------ * ---- * ----- *   ----

7*7    x         1          1

Now we can simplify canceling the 7 terms

3         1        

------ * ----

7         x        

We are left with

3/ 7x
