Whakaoti i te 100/4.5=305/x

$$\frac { 100 } { 4.5 } = \frac { 305 } { x }$$

Whakaoti mō x

$$x=13.725$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.

$$x\times \frac{100}{4.5}=305$$

Whakarohaina te \frac{100}{4.5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x\times \frac{1000}{45}=305$$

Whakahekea te hautanga \frac{1000}{45} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x\times \frac{200}{9}=305$$

Me whakarea ngā taha e rua ki te \frac{9}{200}, te tau utu o \frac{200}{9}.

$$x=305\times \frac{9}{200}$$

Tuhia te 305\times \frac{9}{200} hei hautanga kotahi.

$$x=\frac{305\times 9}{200}$$

Whakareatia te 305 ki te 9, ka 2745.

$$x=\frac{2745}{200}$$

Whakahekea te hautanga \frac{2745}{200} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x=\frac{549}{40}$$
