\(A=\dfrac{1}{3}\left(\dfrac{1}{3}\dfrac{1}{6}+\dfrac{1}{6}\dfrac{1}{9}+...+\dfrac{1}{123}\dfrac{1}{126}\right)\)
\(A=\dfrac{1}{3}\left(\dfrac{1}{3}\dfrac{1}{126}\right)=\dfrac{1}{3}\cdot\dfrac{41}{126}=\dfrac{41}{378}\)
So \(A=\dfrac{41}{378}\)

We see that:
\(\dfrac{1}{3.6}\)=\(\dfrac{1}{3}\). \(\dfrac{3}{3.6}\)=\(\dfrac{1}{3}\). \(\dfrac{1}{3}\) \(\dfrac{1}{6}\)
=>A=\(\dfrac{1}{3}\). \(\dfrac{1}{3}\) \(\dfrac{1}{6}\)+ \(\dfrac{1}{6}\) \(\dfrac{1}{9}\)+...+\(\dfrac{1}{123}\) \(\dfrac{1}{126}\)
=\(\dfrac{1}{3}\). \(\dfrac{1}{3}\) \(\dfrac{1}{126}\)
=\(\dfrac{41}{378}\)

Answer:
From the first division, we formulate the relation as A= 54L+38, Where L is some integer. The second relationship gives A=18 × 14+ R with r ∈ n and $0
A=54x + 38=18 × 3x + 18 × 2 + 2=18(3x + 2)+2
Hence R=2 and A= 18 × 4 + 2= 254
Answer is: A + R=256
Good luck

The last 6 more people must have you Help you solve math :))
I've search some newest users, I can't understand if a question the thread just have the order "Calculate" in hundred kind ( 250 + 100 + ... = ?) you have more than 5 ers in each question.
I've also find some new users and find out that more than 70% new users are your own accounts, cause when I click in that accounts I will find a line that "............. d an answer of a question" when I click in that question, I always find out that you're in that question.
You also for another accounts to low down the doubt that the accounts are yours.
These ways of cheating cannot pass my eyes dude :)) I've catched redhanded a lot of cheating ways that you've never think once in your life.
