Whakaoti i te 1-7/9/14/45

$$1 - \frac { 7 } { 9 } / \frac { 14 } { 45 }$$

Aromātai

$$-\frac{3}{2}=-1.5$$

Ngā Upane Otinga

Whakawehe \frac{7}{9} ki te \frac{14}{45} mā te whakarea \frac{7}{9} ki te tau huripoki o \frac{14}{45}.

$$1-\frac{7}{9}\times \frac{45}{14}$$

Me whakarea te \frac{7}{9} ki te \frac{45}{14} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$1-\frac{7\times 45}{9\times 14}$$

Mahia ngā whakarea i roto i te hautanga \frac{7\times 45}{9\times 14}.

$$1-\frac{315}{126}$$

Whakahekea te hautanga \frac{315}{126} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 63.

$$1-\frac{5}{2}$$

Me tahuri te 1 ki te hautau \frac{2}{2}.

$$\frac{2}{2}-\frac{5}{2}$$

Tā te mea he rite te tauraro o \frac{2}{2} me \frac{5}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{2-5}{2}$$

Tangohia te 5 i te 2, ka -3.

$$-\frac{3}{2}$$

Tauwehe

$$-\frac{3}{2} = -1\frac{1}{2} = -1.5$$
