Aromātai

$$\frac{5}{7}\approx 0.714285714$$

Ngā Upane Otinga

Me whakarea te \frac{5}{7} ki te \frac{3}{8} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{5\times 3}{7\times 8}+\frac{5}{8}\times \frac{5}{7}$$

Mahia ngā whakarea i roto i te hautanga \frac{5\times 3}{7\times 8}.

$$\frac{15}{56}+\frac{5}{8}\times \frac{5}{7}$$

Me whakarea te \frac{5}{8} ki te \frac{5}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{15}{56}+\frac{5\times 5}{8\times 7}$$

Mahia ngā whakarea i roto i te hautanga \frac{5\times 5}{8\times 7}.

$$\frac{15}{56}+\frac{25}{56}$$

Tā te mea he rite te tauraro o \frac{15}{56} me \frac{25}{56}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{15+25}{56}$$

Tāpirihia te 15 ki te 25, ka 40.

$$\frac{40}{56}$$

Whakahekea te hautanga \frac{40}{56} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.

$$\frac{5}{7}$$

Tauwehe
