Whakaoti i te 45.5+(6.8*4.5)-4/12=

$$45.5 + ( 6.8 \times 4.5 ) - \frac { 4 } { 12 } =$$

Aromātai

$$\frac{2273}{30}\approx 75.766666667$$

Ngā Upane Otinga

Whakareatia te 6.8 ki te 4.5, ka 30.6.

$$45.5+30.6-\frac{4}{12}$$

Tāpirihia te 45.5 ki te 30.6, ka 76.1.

$$76.1-\frac{4}{12}$$

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

$$76.1-\frac{1}{3}$$

Me tahuri ki tau ā-ira 76.1 ki te hautau \frac{761}{10}.

$$\frac{761}{10}-\frac{1}{3}$$

Ko te maha noa iti rawa atu o 10 me 3 ko 30. Me tahuri \frac{761}{10} me \frac{1}{3} ki te hautau me te tautūnga 30.

$$\frac{2283}{30}-\frac{10}{30}$$

Tā te mea he rite te tauraro o \frac{2283}{30} me \frac{10}{30}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{2283-10}{30}$$

Tangohia te 10 i te 2283, ka 2273.

$$\frac{2273}{30}$$

Tauwehe

$$\frac{2273}{2 \cdot 3 \cdot 5} = 75\frac{23}{30} = 75.76666666666667$$
