Kua tāruatia ki te papatopenga
\frac{525}{1500}+0.4295
Whakarohaina te \frac{5.25}{15} mā te whakarea i te taurunga me te tauraro ki te 100.
\frac{7}{20}+0.4295
Whakahekea te hautanga \frac{525}{1500} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 75.
\frac{7}{20}+\frac{859}{2000}
Me tahuri ki tau ā-ira 0.4295 ki te hautau \frac{4295}{10000}. Whakahekea te hautanga \frac{4295}{10000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
\frac{700}{2000}+\frac{859}{2000}
Ko te maha noa iti rawa atu o 20 me 2000 ko 2000. Me tahuri \frac{7}{20} me \frac{859}{2000} ki te hautau me te tautūnga 2000.
\frac{700+859}{2000}
Tā te mea he rite te tauraro o \frac{700}{2000} me \frac{859}{2000}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{1559}{2000}
Tāpirihia te 700 ki te 859, ka 1559.
