Whakaoti i te {c}{(-25/4)-(-13/4)}{(+5/4)-(+1/5)}

$$\left. \begin{array} { c } { ( - \frac { 25 } { 4 } ) - ( - \frac { 13 } { 4 } ) } \\ { ( + \frac { 5 } { 4 } ) - ( + \frac { 1 } { 5 } ) } \end{array} \right.$$

Ko te tauaro o -\frac{13}{4} ko \frac{13}{4}.

$$sort(-\frac{25}{4}+\frac{13}{4},\frac{5}{4}-\frac{1}{5})$$

Tā te mea he rite te tauraro o -\frac{25}{4} me \frac{13}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$sort(\frac{-25+13}{4},\frac{5}{4}-\frac{1}{5})$$

Tāpirihia te -25 ki te 13, ka -12.

$$sort(\frac{-12}{4},\frac{5}{4}-\frac{1}{5})$$

Whakawehea te -12 ki te 4, kia riro ko -3.

$$sort(-3,\frac{5}{4}-\frac{1}{5})$$

Ko te maha noa iti rawa atu o 4 me 5 ko 20. Me tahuri \frac{5}{4} me \frac{1}{5} ki te hautau me te tautūnga 20.

$$sort(-3,\frac{25}{20}-\frac{4}{20})$$

Tā te mea he rite te tauraro o \frac{25}{20} me \frac{4}{20}, me tango rāua mā te tango i ō raua taurunga.

$$sort(-3,\frac{25-4}{20})$$

Tangohia te 4 i te 25, ka 21.

$$sort(-3,\frac{21}{20})$$

Tahuritia ngā tau ā-ira i te rārangi -3,\frac{21}{20} ki ngā hautanga.
