$$- \frac { 3 } { 5 } \div ( \frac { 2 } { 7 } \times 1 \frac { 1 } { 4 } )$$

Aromātai

$$-\frac{42}{25}=-1.68$$

Ngā Upane Otinga

Whakareatia te 1 ki te 4, ka 4.

$$\frac{-\frac{3}{5}}{\frac{2}{7}\times \frac{4+1}{4}}$$

Tāpirihia te 4 ki te 1, ka 5.

$$\frac{-\frac{3}{5}}{\frac{2}{7}\times \frac{5}{4}}$$

Me whakarea te \frac{2}{7} ki te \frac{5}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-\frac{3}{5}}{\frac{2\times 5}{7\times 4}}$$

Mahia ngā whakarea i roto i te hautanga \frac{2\times 5}{7\times 4}.

$$\frac{-\frac{3}{5}}{\frac{10}{28}}$$

Whakahekea te hautanga \frac{10}{28} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{-\frac{3}{5}}{\frac{5}{14}}$$

Whakawehe -\frac{3}{5} ki te \frac{5}{14} mā te whakarea -\frac{3}{5} ki te tau huripoki o \frac{5}{14}.

$$-\frac{3}{5}\times \frac{14}{5}$$

Me whakarea te -\frac{3}{5} ki te \frac{14}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-3\times 14}{5\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{-3\times 14}{5\times 5}.

$$\frac{-42}{25}$$

Ka taea te hautanga \frac{-42}{25} te tuhi anō ko -\frac{42}{25} mā te tango i te tohu tōraro.

$$-\frac{42}{25}$$

Tauwehe

$$-\frac{42}{25} = -1\frac{17}{25} = -1.68$$
