Ok so let's start by the basic, 7-4 is 3,and 5-2 is 3.The denominator stays the same so you're left with, 3 3/8
840
10% =84 (840/10)
5% =42 (84/2 or 840/20)
therefore 840+42=882
The answer will be 36.9. Hope this helps

Answer:
I would rather use their multiples.
Step-by-step explanation:
With 13 and 14, neither number has many factors (and few prime factors, for that matter) so factoring would be pretty much useless. If you wanted to use the prime factors of 14 (7 and 2) multiplying either of them by 13 would not give you the LCM. Actually the LCM is just 13*14 which is 182.
Good luck!
