Diwarung bu ani tersedia 20 ⅔ liter minyak,terjual 11 ½ liter,lalu ia membeli lagi 15 ¾ liter. berapa liter minyak yg tersedia diwarung bu ani sekarang?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Diket :
tersedia 20 ⅔ liter
,terjual 11 ½ liter
------------------------------
= 20 2/3 - 11 1/2
= 62/3 - 23/2

= 124/6 - 69/6
= 55 / 6 liter

kemudian membeli lagi 15 ¾ liter
maka :

= 55 / 6 liter + 15 ¾ liter

= 55/6 + 63/4

= 110/12 + 189/12

= 299/12 

= 24 11/12 liter
