Step-by-step explanation:
So I would start by multiplying all the numbers on
the denominator first ----->
11 x 14 = 154
~~~
14 x 17 = 238
~~~ *BASICALLY: FIND THE COMMON DENOMINATOR*
17 x 20 = 340 (this will be how u add everything at the end)
~~~
20 x 23 = 460
Now your goal is to get all of these numbers to be the same as the denominator so you can add them together at the end (get a common denominator)
**(remember when multipling the top and the bottom numbers, whatever you do to the bottom you must do to the top)**
3 3 3 3
--------- (x ?) + --------- (x ?) + --------- (x ?) + --------- =
154 238 340 460
***sorry i dont hav time to finnish but i hope this helped at least a little****
