Whakaoti i te 18/5/frac{2{25}-5/16}

$$\frac{ \frac{ 18 }{ 5 } }{ \frac{ 2 }{ 25 } - \frac{ 5 }{ 16 } }$$

Aromātai

$$-\frac{480}{31}\approx -15.483870968$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 25 me 16 ko 400. Me tahuri \frac{2}{25} me \frac{5}{16} ki te hautau me te tautūnga 400.

$$\frac{\frac{18}{5}}{\frac{32}{400}-\frac{125}{400}}$$

Tā te mea he rite te tauraro o \frac{32}{400} me \frac{125}{400}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{18}{5}}{\frac{32-125}{400}}$$

Tangohia te 125 i te 32, ka -93.

$$\frac{\frac{18}{5}}{-\frac{93}{400}}$$

Whakawehe \frac{18}{5} ki te -\frac{93}{400} mā te whakarea \frac{18}{5} ki te tau huripoki o -\frac{93}{400}.

$$\frac{18}{5}\left(-\frac{400}{93}\right)$$

Me whakarea te \frac{18}{5} ki te -\frac{400}{93} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{18\left(-400\right)}{5\times 93}$$

Mahia ngā whakarea i roto i te hautanga \frac{18\left(-400\right)}{5\times 93}.

$$\frac{-7200}{465}$$

Whakahekea te hautanga \frac{-7200}{465} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 15.

$$-\frac{480}{31}$$

Tauwehe

$$-\frac{480}{31} = -15\frac{15}{31} = -15.483870967741936$$
