Whakaoti i te (1-3/1)div2/3+1/18=

$$(1- \frac{ 3 }{ 1 } ) \div \frac{ 2 }{ 3 } + \frac{ 1 }{ 18 } =$$

Aromātai

$$-\frac{53}{18}\approx -2.944444444$$

Ngā Upane Otinga

Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$\frac{1-3}{\frac{2}{3}}+\frac{1}{18}$$

Tangohia te 3 i te 1, ka -2.

$$\frac{-2}{\frac{2}{3}}+\frac{1}{18}$$

Whakawehe -2 ki te \frac{2}{3} mā te whakarea -2 ki te tau huripoki o \frac{2}{3}.

$$-2\times \frac{3}{2}+\frac{1}{18}$$

Whakareatia -2 ki te \frac{3}{2}.

$$-3+\frac{1}{18}$$

Me tahuri te -3 ki te hautau -\frac{54}{18}.

$$-\frac{54}{18}+\frac{1}{18}$$

Tā te mea he rite te tauraro o -\frac{54}{18} me \frac{1}{18}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-54+1}{18}$$

Tāpirihia te -54 ki te 1, ka -53.

$$-\frac{53}{18}$$

Tauwehe

$$-\frac{53}{18} = -2\frac{17}{18} = -2.9444444444444446$$
