Whakaoti i te (3/2*4)(5/12*3):3

$$( \frac { 3 } { 2 } \cdot 4 ) ( \frac { 5 } { 12 } \cdot 3 ) : 3$$

Aromātai

$$\frac{5}{2}=2.5$$

Ngā Upane Otinga

Me whakakore te 3 me te 3.

$$\frac{3}{2}\times 4\times \frac{5}{12}$$

Tuhia te \frac{3}{2}\times 4 hei hautanga kotahi.

$$\frac{3\times 4}{2}\times \frac{5}{12}$$

Whakareatia te 3 ki te 4, ka 12.

$$\frac{12}{2}\times \frac{5}{12}$$

Whakawehea te 12 ki te 2, kia riro ko 6.

$$6\times \frac{5}{12}$$

Tuhia te 6\times \frac{5}{12} hei hautanga kotahi.

$$\frac{6\times 5}{12}$$

Whakareatia te 6 ki te 5, ka 30.

$$\frac{30}{12}$$

Whakahekea te hautanga \frac{30}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.

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

Tauwehe

$$\frac{5}{2} = 2\frac{1}{2} = 2.5$$
