Whakaoti i te 34/15*5/7+2.6

$$3 \frac { 4 } { 15 } \times \frac { 5 } { 7 } + 2.6$$

Aromātai

$$\frac{74}{15}\approx 4.933333333$$

Ngā Upane Otinga

Whakareatia te 3 ki te 15, ka 45.

$$\frac{45+4}{15}\times \frac{5}{7}+2.6$$

Tāpirihia te 45 ki te 4, ka 49.

$$\frac{49}{15}\times \frac{5}{7}+2.6$$

Me whakarea te \frac{49}{15} ki te \frac{5}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{49\times 5}{15\times 7}+2.6$$

Mahia ngā whakarea i roto i te hautanga \frac{49\times 5}{15\times 7}.

$$\frac{245}{105}+2.6$$

Whakahekea te hautanga \frac{245}{105} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 35.

$$\frac{7}{3}+2.6$$

Me tahuri ki tau ā-ira 2.6 ki te hautau \frac{26}{10}. Whakahekea te hautanga \frac{26}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{7}{3}+\frac{13}{5}$$

Ko te maha noa iti rawa atu o 3 me 5 ko 15. Me tahuri \frac{7}{3} me \frac{13}{5} ki te hautau me te tautūnga 15.

$$\frac{35}{15}+\frac{39}{15}$$

Tā te mea he rite te tauraro o \frac{35}{15} me \frac{39}{15}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{35+39}{15}$$

Tāpirihia te 35 ki te 39, ka 74.

$$\frac{74}{15}$$

Tauwehe

$$\frac{2 \cdot 37}{3 \cdot 5} = 4\frac{14}{15} = 4.933333333333334$$
