1) 2a²
---------
4a
= (2a)(a)
------------
(2a)(2)
= a / 2

2) (3 / 2x ) + (4 / x+2 )
= 3(x + 2) + 4(2x)
--------------------------
(x + 2)(2x)
= 3x + 6 + 8x
--------------------
(x + 2)(2x)
= 11x + 6
--------------
2x² + 4x

3) (3 / p) - (2 / p+1 )
= 3(p + 1) - 2(p)
-----------------------
(p + 1)(p)
= 3p + 3 - 2p
---------------------
p² + p
= p + 3
-------------
p² + p

4) (3w / 4 ) - (w+1 / 2)
= 3w(2) - 4(w + 1)
----------------------------
(4)(2)
= 6w - 4w - 4
--------------------
8
= 2w - 4
--------------
8
= 2(w - 2)
--------------
(2)(4)
= w - 2
------------
4

5) { (4p / 6) ÷ (p² / 12) } × ½
= { (4p / 6) × (12 / p²)} × ½
= { (4 . 2) / (1 . p)} × ½
= ( 8 / p ) × ½
= 4
-------
p
