Ngā Upane mō te Whakaoti Whārite Rārangi

Whakahekea te hautanga \frac{15}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x\times \frac{3}{20}\times \frac{20}{100}=7452$$

Whakahekea te hautanga \frac{20}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$x\times \frac{3}{20}\times \frac{1}{5}=7452$$

Me whakarea te \frac{3}{20} ki te \frac{1}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x\times \frac{3\times 1}{20\times 5}=7452$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 1}{20\times 5}.

$$x\times \frac{3}{100}=7452$$

Me whakarea ngā taha e rua ki te \frac{100}{3}, te tau utu o \frac{3}{100}.

$$x=7452\times \frac{100}{3}$$

Tuhia te 7452\times \frac{100}{3} hei hautanga kotahi.

$$x=\frac{7452\times 100}{3}$$

Whakareatia te 7452 ki te 100, ka 745200.

$$x=\frac{745200}{3}$$

Whakawehea te 745200 ki te 3, kia riro ko 248400.

$$x=248400$$
