\frac{799}{1000}-\frac{25}{100}
Whakarohaina te \frac{79.9}{100} mā te whakarea i te taurunga me te tauraro ki te 10.
\frac{799}{1000}-\frac{1}{4}
Whakahekea te hautanga \frac{25}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.
\frac{799}{1000}-\frac{250}{1000}
Ko te maha noa iti rawa atu o 1000 me 4 ko 1000. Me tahuri \frac{799}{1000} me \frac{1}{4} ki te hautau me te tautūnga 1000.
\frac{799-250}{1000}
Tā te mea he rite te tauraro o \frac{799}{1000} me \frac{250}{1000}, me tango rāua mā te tango i ō raua taurunga.
\frac{549}{1000}
Tangohia te 250 i te 799, ka 549.
