Whakaoti i te 5/100X7/10

$$\frac { 5 } { 100 } X \frac { 7 } { 10 }$$

Aromātai

$$\frac{7X}{200}$$

Ngā Upane Otinga

Whakahekea te hautanga \frac{5}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{1}{20}X\times \frac{7}{10}$$

Me whakarea te \frac{1}{20} ki te \frac{7}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1\times 7}{20\times 10}X$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 7}{20\times 10}.

$$\frac{7}{200}X$$

Kimi Pārōnaki e ai ki X

$$\frac{7}{200} = 0.035$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Whakahekea te hautanga \frac{5}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{\mathrm{d}}{\mathrm{d}X}(\frac{1}{20}X\times \frac{7}{10})$$

Me whakarea te \frac{1}{20} ki te \frac{7}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{\mathrm{d}}{\mathrm{d}X}(\frac{1\times 7}{20\times 10}X)$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 7}{20\times 10}.

$$\frac{\mathrm{d}}{\mathrm{d}X}(\frac{7}{200}X)$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$\frac{7}{200}X^{1-1}$$

Tango 1 mai i 1.

$$\frac{7}{200}X^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.

$$\frac{7}{200}\times 1$$

Mō tētahi kupu t, t\times 1=t me 1t=t.

$$\frac{7}{200}$$
