Kua tāruatia ki te papatopenga
450\left(1-\frac{1}{10}\right)
Whakahekea te hautanga \frac{10}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.
450\left(\frac{10}{10}-\frac{1}{10}\right)
Me tahuri te 1 ki te hautau \frac{10}{10}.
450\times \frac{10-1}{10}
Tā te mea he rite te tauraro o \frac{10}{10} me \frac{1}{10}, me tango rāua mā te tango i ō raua taurunga.
450\times \frac{9}{10}
Tangohia te 1 i te 10, ka 9.
\frac{450\times 9}{10}
Tuhia te 450\times \frac{9}{10} hei hautanga kotahi.
\frac{4050}{10}
Whakareatia te 450 ki te 9, ka 4050.
405
Whakawehea te 4050 ki te 10, kia riro ko 405.
