Me whakarea te \frac{7}{8} ki te \frac{5}{16} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{7\times 5}{8\times 16}-\frac{3}{16}\times \frac{5}{8}$$

Mahia ngā whakarea i roto i te hautanga \frac{7\times 5}{8\times 16}.

$$\frac{35}{128}-\frac{3}{16}\times \frac{5}{8}$$

Me whakarea te \frac{3}{16} ki te \frac{5}{8} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{35}{128}-\frac{3\times 5}{16\times 8}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 5}{16\times 8}.

$$\frac{35}{128}-\frac{15}{128}$$

Tā te mea he rite te tauraro o \frac{35}{128} me \frac{15}{128}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{35-15}{128}$$

Tangohia te 15 i te 35, ka 20.

$$\frac{20}{128}$$

Whakahekea te hautanga \frac{20}{128} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
