Whakahekea te hautanga \frac{4}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$18-\frac{1}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

Me tahuri te 18 ki te hautau \frac{450}{25}.

$$\frac{450}{25}-\frac{1}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

Tā te mea he rite te tauraro o \frac{450}{25} me \frac{1}{25}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{450-1}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

Tangohia te 1 i te 450, ka 449.

$$\frac{449}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

Ko te maha noa iti rawa atu o 25 me 100 ko 100. Me tahuri \frac{449}{25} me \frac{3}{100} ki te hautau me te tautūnga 100.
