3 ÷ (5 ÷ 7) = (3 ÷ 5) ÷ 7

___________________________________________

Answer
    None
Explanation

The above question is look like it is true for associative law. But associative law does not work for division.

Let us solve the above statement by taking L.H.S. and R.H.S.


    3 ÷ (5 ÷ 7) = (3 ÷ 5) ÷ 7

    L.H.S.
    3 ÷ (5 ÷ 7) 
    = 3 ÷ (5/7)
    = 3 × (7/5)
    = 21/5
    
    R.H.S.
    (3 ÷ 5) ÷ 7
    = (3/5) ÷ 7
    = (3/5) × (1/7)
    = (3/35)
                    
    3 ÷ (5 ÷ 7) ≠ (3 ÷ 5) ÷ 7

Therefore above statement is false and answer is 'none'
