Whakahekea te hautanga \frac{150}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 50.

$$\frac{3}{2}\times 15+\frac{75}{100}\times 75$$

Tuhia te \frac{3}{2}\times 15 hei hautanga kotahi.

$$\frac{3\times 15}{2}+\frac{75}{100}\times 75$$

Whakareatia te 3 ki te 15, ka 45.

$$\frac{45}{2}+\frac{75}{100}\times 75$$

Whakahekea te hautanga \frac{75}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{45}{2}+\frac{3}{4}\times 75$$

Tuhia te \frac{3}{4}\times 75 hei hautanga kotahi.

$$\frac{45}{2}+\frac{3\times 75}{4}$$

Whakareatia te 3 ki te 75, ka 225.

$$\frac{45}{2}+\frac{225}{4}$$

Ko te maha noa iti rawa atu o 2 me 4 ko 4. Me tahuri \frac{45}{2} me \frac{225}{4} ki te hautau me te tautūnga 4.

$$\frac{90}{4}+\frac{225}{4}$$

Tā te mea he rite te tauraro o \frac{90}{4} me \frac{225}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{90+225}{4}$$

Tāpirihia te 90 ki te 225, ka 315.

$$\frac{315}{4}$$

Tauwehe

$$\frac{3 ^ {2} \cdot 5 \cdot 7}{2 ^ {2}} = 78\frac{3}{4} = 78.75$$
