Whakaoti i te 45.5+(68*45)-4/12

$$45.5 + ( 68 \times 45 ) - \frac { 4 } { 12 }$$

Aromātai

$$\frac{18631}{6}\approx 3105.166666667$$

Ngā Upane Otinga

Whakareatia te 68 ki te 45, ka 3060.

$$45.5+3060-\frac{4}{12}$$

Tāpirihia te 45.5 ki te 3060, ka 3105.5.

$$3105.5-\frac{4}{12}$$

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

$$3105.5-\frac{1}{3}$$

Me tahuri ki tau ā-ira 3105.5 ki te hautau \frac{31055}{10}. Whakahekea te hautanga \frac{31055}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{6211}{2}-\frac{1}{3}$$

Ko te maha noa iti rawa atu o 2 me 3 ko 6. Me tahuri \frac{6211}{2} me \frac{1}{3} ki te hautau me te tautūnga 6.

$$\frac{18633}{6}-\frac{2}{6}$$

Tā te mea he rite te tauraro o \frac{18633}{6} me \frac{2}{6}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{18633-2}{6}$$

Tangohia te 2 i te 18633, ka 18631.

$$\frac{18631}{6}$$

Tauwehe

$$\frac{31 \cdot 601}{2 \cdot 3} = 3105\frac{1}{6} = 3105.1666666666665$$
