Whakaoti i te x*39/158div158=25%

$$x \times \frac{ 39 }{ 158 } \div 158=25 \%$$

Whakaoti mō x

$$x = \frac{6241}{39} = 160\frac{1}{39} \approx 160.025641026$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 7900, arā, te tauraro pātahi he tino iti rawa te kitea o 158,100.

$$50x\times \frac{39}{158}=79\times 25$$

Tuhia te 50\times \frac{39}{158} hei hautanga kotahi.

$$\frac{50\times 39}{158}x=79\times 25$$

Whakareatia te 50 ki te 39, ka 1950.

$$\frac{1950}{158}x=79\times 25$$

Whakahekea te hautanga \frac{1950}{158} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{975}{79}x=79\times 25$$

Whakareatia te 79 ki te 25, ka 1975.

$$\frac{975}{79}x=1975$$

Me whakarea ngā taha e rua ki te \frac{79}{975}, te tau utu o \frac{975}{79}.

$$x=1975\times \frac{79}{975}$$

Tuhia te 1975\times \frac{79}{975} hei hautanga kotahi.

$$x=\frac{1975\times 79}{975}$$

Whakareatia te 1975 ki te 79, ka 156025.

$$x=\frac{156025}{975}$$

Whakahekea te hautanga \frac{156025}{975} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$x=\frac{6241}{39}$$
