Whakaoti i te 196-2:7(1.2-1-0.25)

$$196 - 2 : 7 ( 1.2 - 1 - 0.25 )$$

Aromātai

$$\frac{13721}{70}\approx 196.014285714$$

Ngā Upane Otinga

Tangohia te 1 i te 1.2, ka 0.2.

$$196-\frac{2}{7}\left(0.2-0.25\right)$$

Tangohia te 0.25 i te 0.2, ka -0.05.

$$196-\frac{2}{7}\left(-0.05\right)$$

Me tahuri ki tau ā-ira -0.05 ki te hautau -\frac{5}{100}. Whakahekea te hautanga -\frac{5}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$196-\frac{2}{7}\left(-\frac{1}{20}\right)$$

Me whakarea te \frac{2}{7} ki te -\frac{1}{20} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$196-\frac{2\left(-1\right)}{7\times 20}$$

Mahia ngā whakarea i roto i te hautanga \frac{2\left(-1\right)}{7\times 20}.

$$196-\frac{-2}{140}$$

Whakahekea te hautanga \frac{-2}{140} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$196-\left(-\frac{1}{70}\right)$$

Ko te tauaro o -\frac{1}{70} ko \frac{1}{70}.

$$196+\frac{1}{70}$$

Me tahuri te 196 ki te hautau \frac{13720}{70}.

$$\frac{13720}{70}+\frac{1}{70}$$

Tā te mea he rite te tauraro o \frac{13720}{70} me \frac{1}{70}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{13720+1}{70}$$

Tāpirihia te 13720 ki te 1, ka 13721.

$$\frac{13721}{70}$$

Tauwehe

$$\frac{13721}{2 \cdot 5 \cdot 7} = 196\frac{1}{70} = 196.0142857142857$$
