  2*(3*4) = 41/16

Step-by-step explanation:

Your function is not carefully defined.* We assume you intend ...

  f(a, b) = (2a +3b)/(a +b)

and you want to find ...

  f(2, f(3, 4))

__

Filling in the values and doing the arithmetic, we have ...

_____

* We have assumed that the definition is describing the result of using the infix operator * in an expression of the form a*b. We have also assumed that your use of the ÷ symbol means ...

  a*b ≡ (2a+3b)/(a+b)

as opposed to the strict Order of Operations interpretation ...

  a*b ≡ 2a + (3b/a) +b

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

y/x of point b= y/x of point a
