Nā manatu o te fuafuaga
- Ko te pahene ma te tau fakavae ni numela moni mahani.
- E heai he tulafono tupe, fakataamilo pe tulafono patino e fakauiga.
- Ko te tali e fakaali e fakaikuga na mō te fakaaliga.
Auala ke fakamatala te tali
- Ko te tali autū ko te pahege kua filifilia o te aogā fakavae.
- Ko te faiga decimal ko te pahene e vaevae ki te 100.
- Ko te uma o te to'e ma te uma o te fakaopoopo e fakaali nā tulaga mahani o te fakaitiiti ma te fakaopoopo.
Nā hē mahani ke kalo kehe mai ai
- Tuku te 0.20 ki he fakamatalaga e manakomia te 20%.
- Manatu ko te 20% fakaopoopoga oi hohoko ai te 20% fakaitiitiga e toe foki ki te tau muamua.
- Vaevae ki te fakavae hē kafai e fuafua te mafuli pahene.
