Whakaoti i te 15.5+(6.8*4.5)-4/12=

$$15.5 + ( 6.8 \times 4.5 ) - \frac { 4 } { 12 } =$$

Aromātai

$$\frac{1373}{30}\approx 45.766666667$$

Ngā Upane Otinga

Whakareatia te 6.8 ki te 4.5, ka 30.6.

$$15.5+30.6-\frac{4}{12}$$

Tāpirihia te 15.5 ki te 30.6, ka 46.1.

$$46.1-\frac{4}{12}$$

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

$$46.1-\frac{1}{3}$$

Me tahuri ki tau ā-ira 46.1 ki te hautau \frac{461}{10}.

$$\frac{461}{10}-\frac{1}{3}$$

Ko te maha noa iti rawa atu o 10 me 3 ko 30. Me tahuri \frac{461}{10} me \frac{1}{3} ki te hautau me te tautūnga 30.

$$\frac{1383}{30}-\frac{10}{30}$$

Tā te mea he rite te tauraro o \frac{1383}{30} me \frac{10}{30}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1383-10}{30}$$

Tangohia te 10 i te 1383, ka 1373.

$$\frac{1373}{30}$$

Tauwehe

$$\frac{1373}{2 \cdot 3 \cdot 5} = 45\frac{23}{30} = 45.766666666666666$$
