Whakaoti i te 100=A_{100}(0.5)1000/25000

$$100 = A _ { 100 } ( 0.5 ) \frac { 1000 } { 25000 }$$

Whakaoti mō A_100

$$A_{100}=5000$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakahekea te hautanga \frac{1000}{25000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 1000.

$$100=A_{100}\times 0.5\times \frac{1}{25}$$

Me tahuri ki tau ā-ira 0.5 ki te hautau \frac{5}{10}. Whakahekea te hautanga \frac{5}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$100=A_{100}\times \frac{1}{2}\times \frac{1}{25}$$

Me whakarea te \frac{1}{2} ki te \frac{1}{25} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$100=A_{100}\times \frac{1\times 1}{2\times 25}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 1}{2\times 25}.

$$100=A_{100}\times \frac{1}{50}$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$A_{100}\times \frac{1}{50}=100$$

Me whakarea ngā taha e rua ki te 50, te tau utu o \frac{1}{50}.

$$A_{100}=100\times 50$$

Whakareatia te 100 ki te 50, ka 5000.

$$A_{100}=5000$$
