Whakaoti i te 1-(4/12+3/12+2/12)=

$$1 - ( \frac { 4 } { 12 } + \frac { 3 } { 12 } + \frac { 2 } { 12 } ) =$$

Aromātai

$$\frac{1}{4}=0.25$$

Ngā Upane Otinga

Tā te mea he rite te tauraro o \frac{4}{12} me \frac{3}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$1-\left(\frac{4+3}{12}+\frac{2}{12}\right)$$

Tāpirihia te 4 ki te 3, ka 7.

$$1-\left(\frac{7}{12}+\frac{2}{12}\right)$$

Tā te mea he rite te tauraro o \frac{7}{12} me \frac{2}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$1-\frac{7+2}{12}$$

Tāpirihia te 7 ki te 2, ka 9.

$$1-\frac{9}{12}$$

Whakahekea te hautanga \frac{9}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$1-\frac{3}{4}$$

Me tahuri te 1 ki te hautau \frac{4}{4}.

$$\frac{4}{4}-\frac{3}{4}$$

Tā te mea he rite te tauraro o \frac{4}{4} me \frac{3}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{4-3}{4}$$

Tangohia te 3 i te 4, ka 1.

$$\frac{1}{4}$$

Tauwehe

$$\frac{1}{2 ^ {2}} = 0.25$$
