11 8 per 9 dikurang 31 per 6 dikurang 41 per 2
11 8/9 – 31/6 – 41/2
= 107/9 -31/6 – 41/2
= 214/18 – 93/18 – 369/18
= -248/18
11 8/9 – 31/6 – 41/2………..[*11 8/9 = 107/9]
107/9 – 31/6 – 41/2……….[samakan penyebut dengan mencari kpk ketiga bilangan,]
kpk = 18
•18:9= 2 x 107 = 214
•18:6= 3 x 31 = 93
•18:2= 9 x 41 = 369
214/18 – 93/18 – 369/18
= – 248/18 = -124/9
