Question

1). X-2/2y - x +9/4y =
* "/" maksudnya per
2). 2p-5/8 ÷ p+2p/16p =

Answer 1

1) (x - 2)/2y - (x + 9)/4y
= 2(x - 2)/4y - (x + 9)/4y
= (2x - x - 4 - 9)/4y
= (x - 13)/4y

2) (2p - 5)/8 ÷ (p + 2p)/16p
= (2p - 5)/8 × 16p/(p + 2p)
= 16p(2p - 5)
-----------------
8(p + 2p)
= 16p(2p - 5)
----------------
8 × 3p
= 16p(2p - 5)
----------------
24p
= ⅔(2p - 5)
