$$24.5$$

Ngā Upane Otinga

Tātaihia te 3.88 mā te pū o 2, kia riro ko 15.0544.

$$\frac{15.0544+3.12^{2}}{2}+3.88\times 3.12$$

Tātaihia te 3.12 mā te pū o 2, kia riro ko 9.7344.

$$\frac{15.0544+9.7344}{2}+3.88\times 3.12$$

Tāpirihia te 15.0544 ki te 9.7344, ka 24.7888.

$$\frac{24.7888}{2}+3.88\times 3.12$$

Whakarohaina te \frac{24.7888}{2} mā te whakarea i te taurunga me te tauraro ki te 10000.

$$\frac{247888}{20000}+3.88\times 3.12$$

Whakahekea te hautanga \frac{247888}{20000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 16.

$$\frac{15493}{1250}+3.88\times 3.12$$

Whakareatia te 3.88 ki te 3.12, ka 12.1056.

$$\frac{15493}{1250}+12.1056$$

Me tahuri ki tau ā-ira 12.1056 ki te hautau \frac{121056}{10000}. Whakahekea te hautanga \frac{121056}{10000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 16.

$$\frac{15493}{1250}+\frac{7566}{625}$$

Ko te maha noa iti rawa atu o 1250 me 625 ko 1250. Me tahuri \frac{15493}{1250} me \frac{7566}{625} ki te hautau me te tautūnga 1250.

$$\frac{15493}{1250}+\frac{15132}{1250}$$

Tā te mea he rite te tauraro o \frac{15493}{1250} me \frac{15132}{1250}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{15493+15132}{1250}$$

Tāpirihia te 15493 ki te 15132, ka 30625.

$$\frac{30625}{1250}$$

Whakahekea te hautanga \frac{30625}{1250} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 625.

$$\frac{49}{2}$$

Tauwehe

$$\frac{7 ^ {2}}{2} = 24\frac{1}{2} = 24.5$$
