Whakaoti i te p/25*80%=14

$$\frac { p } { 25 } \times 80 \% = 14$$

Whakaoti mō p

$$p = \frac{875}{2} = 437\frac{1}{2} = 437.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 100, arā, te tauraro pātahi he tino iti rawa te kitea o 25,100.

$$4p\times \frac{80}{100}=1400$$

Whakahekea te hautanga \frac{80}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$4p\times \frac{4}{5}=1400$$

Tuhia te 4\times \frac{4}{5} hei hautanga kotahi.

$$\frac{4\times 4}{5}p=1400$$

Whakareatia te 4 ki te 4, ka 16.

$$\frac{16}{5}p=1400$$

Me whakarea ngā taha e rua ki te \frac{5}{16}, te tau utu o \frac{16}{5}.

$$p=1400\times \frac{5}{16}$$

Tuhia te 1400\times \frac{5}{16} hei hautanga kotahi.

$$p=\frac{1400\times 5}{16}$$

Whakareatia te 1400 ki te 5, ka 7000.

$$p=\frac{7000}{16}$$

Whakahekea te hautanga \frac{7000}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.

$$p=\frac{875}{2}$$
