Me tahuri ki tau ā-ira 0.88 ki te hautau \frac{88}{100}. Whakahekea te hautanga \frac{88}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{6}{11}\times \frac{22}{25}-\frac{\frac{4}{7}}{\frac{8}{21}}$$

Me whakarea te \frac{6}{11} ki te \frac{22}{25} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{6\times 22}{11\times 25}-\frac{\frac{4}{7}}{\frac{8}{21}}$$

Mahia ngā whakarea i roto i te hautanga \frac{6\times 22}{11\times 25}.

$$\frac{132}{275}-\frac{\frac{4}{7}}{\frac{8}{21}}$$

Whakahekea te hautanga \frac{132}{275} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 11.

$$\frac{12}{25}-\frac{\frac{4}{7}}{\frac{8}{21}}$$

Whakawehe \frac{4}{7} ki te \frac{8}{21} mā te whakarea \frac{4}{7} ki te tau huripoki o \frac{8}{21}.

$$\frac{12}{25}-\frac{4}{7}\times \frac{21}{8}$$

Me whakarea te \frac{4}{7} ki te \frac{21}{8} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{12}{25}-\frac{4\times 21}{7\times 8}$$

Mahia ngā whakarea i roto i te hautanga \frac{4\times 21}{7\times 8}.

$$\frac{12}{25}-\frac{84}{56}$$

Whakahekea te hautanga \frac{84}{56} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 28.

$$\frac{12}{25}-\frac{3}{2}$$

Ko te maha noa iti rawa atu o 25 me 2 ko 50. Me tahuri \frac{12}{25} me \frac{3}{2} ki te hautau me te tautūnga 50.

$$\frac{24}{50}-\frac{75}{50}$$

Tā te mea he rite te tauraro o \frac{24}{50} me \frac{75}{50}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{24-75}{50}$$

Tangohia te 75 i te 24, ka -51.

$$-\frac{51}{50}$$
