Whakaoti i te 3/8(4-2)+3/16(8-4)

$$\frac { 3 } { 8 } ( 4 - 2 ) + \frac { 3 } { 16 } ( 8 - 4 )$$

Aromātai

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

Ngā Upane Otinga

Tangohia te 2 i te 4, ka 2.

$$\frac{3}{8}\times 2+\frac{3}{16}\left(8-4\right)$$

Tuhia te \frac{3}{8}\times 2 hei hautanga kotahi.

$$\frac{3\times 2}{8}+\frac{3}{16}\left(8-4\right)$$

Whakareatia te 3 ki te 2, ka 6.

$$\frac{6}{8}+\frac{3}{16}\left(8-4\right)$$

Whakahekea te hautanga \frac{6}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{3}{4}+\frac{3}{16}\left(8-4\right)$$

Tangohia te 4 i te 8, ka 4.

$$\frac{3}{4}+\frac{3}{16}\times 4$$

Tuhia te \frac{3}{16}\times 4 hei hautanga kotahi.

$$\frac{3}{4}+\frac{3\times 4}{16}$$

Whakareatia te 3 ki te 4, ka 12.

$$\frac{3}{4}+\frac{12}{16}$$

Whakahekea te hautanga \frac{12}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{3}{4}+\frac{3}{4}$$

Tā te mea he rite te tauraro o \frac{3}{4} me \frac{3}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{3+3}{4}$$

Tāpirihia te 3 ki te 3, ka 6.

$$\frac{6}{4}$$

Whakahekea te hautanga \frac{6}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

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

Tauwehe

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