Identify the least common denominator.
8/13, 11/z-4

Sagot :

Answer:

13

Step-by-step explanation:

first, the z-4 is in the denominator, which makes it hard to get it. But a way to get rid of it is by multiplying z-4/z-4 to 11/z-4, which cancels out the z-4 in the denominator

Yay! now we have two numbers that are easier to deal with

8/13 , and 11z-44

since 11z-44 isn't in fraction form, we add one to its denominator.

8/13, and 11z-44/1

multiply 11z-44/1 by 13 to get:

13(11z-44)/13 = 143z-572/13

8/13, 143z-572/13

After all that, the common denominator is 13. *phew*
