$$1.2 \times 1 \frac { 3 } { 7 } \times 0.84$$

Aromātai

$$1.44$$

Ngā Upane Otinga

Whakareatia te 1 ki te 7, ka 7.

$$1.2\times \frac{7+3}{7}\times 0.84$$

Tāpirihia te 7 ki te 3, ka 10.

$$1.2\times \frac{10}{7}\times 0.84$$

Me tahuri ki tau ā-ira 1.2 ki te hautau \frac{12}{10}. Whakahekea te hautanga \frac{12}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{6}{5}\times \frac{10}{7}\times 0.84$$

Me whakarea te \frac{6}{5} ki te \frac{10}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{6\times 10}{5\times 7}\times 0.84$$

Mahia ngā whakarea i roto i te hautanga \frac{6\times 10}{5\times 7}.

$$\frac{60}{35}\times 0.84$$

Whakahekea te hautanga \frac{60}{35} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{12}{7}\times 0.84$$

Me tahuri ki tau ā-ira 0.84 ki te hautau \frac{84}{100}. Whakahekea te hautanga \frac{84}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{12}{7}\times \frac{21}{25}$$

Me whakarea te \frac{12}{7} ki te \frac{21}{25} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{12\times 21}{7\times 25}$$

Mahia ngā whakarea i roto i te hautanga \frac{12\times 21}{7\times 25}.

$$\frac{252}{175}$$

Whakahekea te hautanga \frac{252}{175} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$\frac{36}{25}$$

Tauwehe

$$\frac{2 ^ {2} \cdot 3 ^ {2}}{5 ^ {2}} = 1\frac{11}{25} = 1.44$$
