Fractions with sum 1 Using all numbers 0 to 9 only once, form two fractions whose sum is 1.I have tried every possible combination but with no luck. I believe the fractions must be xx/xx + xxx/xxx but I am not sure. Any ideas are most welcome. I even tried getting all different ways to select 3 out of 10 digits, then omitting all the primes and trying to make fractions with simple values 1/3, 1/4, 2/5 etc using only different digits but again with no luck! By the way, two years ago I was given a similar one, with three fractions and without the digit 0, for which I found a solution 7/68+9/12+5/34 but now I am stuck!!

27 054 + 69 138 = 1 2 + 1 2 = 1
Or if a leading zero is not allowed.
135 270 + 48 96 = 1 2 + 1 2 = 1

Simplifying fraction with square root as denominator
I'm trying to find the integral of:
2 x 3 x + x 2 x
but I first need to simplify it so I tried dividing by the x for each of the numbers on the top like so:
2 x x
and did the same for the others. For the one above it was easy to see that it just simplifies to 2. But I am unsure how to do the same for the others for instance 3 x x I know to x but i don't know what 3 x x would come out with?

Inequality b a b + b + 1 + c b c + c + 1 + a a c + a + 1 3 m m 2 + m + 1
Let m = ( a b c ) 1 3 , where a , b , c R + . Then prove that
b a b + b + 1 + c b c + c + 1 + a a c + a + 1 3 m m 2 + m + 1
In this inequality I first applied Titu's lemma ; then Rhs will come 9/(some terms) ; now to maximise the rhs I tried to minimise the denominator by applying AM-GM inequality.But then the reverse inequality is coming Please help.

Inequality - GM, AM, HM and SM means
I've got stuck at this problem :
Prove that for any a > 0 and any b > 0 the following inequality is true:
3 ( a 3 b 3 + b 3 a 3 ) a b + b a + 4
The first thing that I've thought was the AM-GM inequality (the extended version - heard that is also known as The power mean inequality):
H M G M A M S M
where H M, G M, A M, and S M refer to the harmonic, geometric, arithmetic, and square mean, respectively. CBS(Cauchy - Buniakowsky - Schwartz) also come to my mind, but I think it isn't helpful in this case.
I would be greatful for some hints.
Thanks!

Find arctan ( 1 3 ) + arctan ( 1 9 ) + arctan ( 7 19 )
Firstly used this formula
arctan ( α ) + arctan ( β ) = arctan ( 1 x y x + y ) , x > 0 , y > 0 = arctan ( 1 1 3 1 9 1 3 + 1 9 ) = arctan ( 2 )
So it is arctan ( 2 ) + arctan ( 7 19 ) .
