Ngā Upane Otinga

Tāpirihia te 42.5 ki te 1, ka 43.5.

$$\frac{2.5+\frac{43.5}{25-2}}{\frac{1}{25}}+1$$

Tangohia te 2 i te 25, ka 23.

$$\frac{2.5+\frac{43.5}{23}}{\frac{1}{25}}+1$$

Whakarohaina te \frac{43.5}{23} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{2.5+\frac{435}{230}}{\frac{1}{25}}+1$$

Whakahekea te hautanga \frac{435}{230} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{2.5+\frac{87}{46}}{\frac{1}{25}}+1$$

Me tahuri ki tau ā-ira 2.5 ki te hautau \frac{25}{10}. Whakahekea te hautanga \frac{25}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{\frac{5}{2}+\frac{87}{46}}{\frac{1}{25}}+1$$

Ko te maha noa iti rawa atu o 2 me 46 ko 46. Me tahuri \frac{5}{2} me \frac{87}{46} ki te hautau me te tautūnga 46.

$$\frac{\frac{115}{46}+\frac{87}{46}}{\frac{1}{25}}+1$$

Tā te mea he rite te tauraro o \frac{115}{46} me \frac{87}{46}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{\frac{115+87}{46}}{\frac{1}{25}}+1$$

Tāpirihia te 115 ki te 87, ka 202.

$$\frac{\frac{202}{46}}{\frac{1}{25}}+1$$

Whakahekea te hautanga \frac{202}{46} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{\frac{101}{23}}{\frac{1}{25}}+1$$

Whakawehe \frac{101}{23} ki te \frac{1}{25} mā te whakarea \frac{101}{23} ki te tau huripoki o \frac{1}{25}.

$$\frac{101}{23}\times 25+1$$

Tuhia te \frac{101}{23}\times 25 hei hautanga kotahi.

$$\frac{101\times 25}{23}+1$$

Whakareatia te 101 ki te 25, ka 2525.

$$\frac{2525}{23}+1$$

Me tahuri te 1 ki te hautau \frac{23}{23}.

$$\frac{2525}{23}+\frac{23}{23}$$

Tā te mea he rite te tauraro o \frac{2525}{23} me \frac{23}{23}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{2525+23}{23}$$

Tāpirihia te 2525 ki te 23, ka 2548.

$$\frac{2548}{23}$$

Tauwehe

$$\frac{13 \cdot 2 ^ {2} \cdot 7 ^ {2}}{23} = 110\frac{18}{23} = 110.78260869565217$$
