$$1-( \frac{ 4 }{ 12 } + \frac{ 3 }{ 18 } )$$

Aromātai

$$\frac{1}{2}=0.5$$

Ngā Upane Otinga

Whakahekea te hautanga \frac{4}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$1-\left(\frac{1}{3}+\frac{3}{18}\right)$$

Whakahekea te hautanga \frac{3}{18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$1-\left(\frac{1}{3}+\frac{1}{6}\right)$$

Ko te maha noa iti rawa atu o 3 me 6 ko 6. Me tahuri \frac{1}{3} me \frac{1}{6} ki te hautau me te tautūnga 6.

$$1-\left(\frac{2}{6}+\frac{1}{6}\right)$$

Tā te mea he rite te tauraro o \frac{2}{6} me \frac{1}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$1-\frac{2+1}{6}$$

Tāpirihia te 2 ki te 1, ka 3.

$$1-\frac{3}{6}$$

Whakahekea te hautanga \frac{3}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$1-\frac{1}{2}$$

Me tahuri te 1 ki te hautau \frac{2}{2}.

$$\frac{2}{2}-\frac{1}{2}$$

Tā te mea he rite te tauraro o \frac{2}{2} me \frac{1}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{2-1}{2}$$

Tangohia te 1 i te 2, ka 1.

$$\frac{1}{2}$$

Tauwehe

$$\frac{1}{2} = 0.5$$
