Me tahuri te 5 ki te hautau \frac{200}{40}.

$$\frac{25}{2}-\left(\frac{200}{40}-\frac{133}{40}-\frac{1}{2}\right)-11-\frac{13}{40}$$

Tā te mea he rite te tauraro o \frac{200}{40} me \frac{133}{40}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{25}{2}-\left(\frac{200-133}{40}-\frac{1}{2}\right)-11-\frac{13}{40}$$

Tangohia te 133 i te 200, ka 67.

$$\frac{25}{2}-\left(\frac{67}{40}-\frac{1}{2}\right)-11-\frac{13}{40}$$

Ko te maha noa iti rawa atu o 40 me 2 ko 40. Me tahuri \frac{67}{40} me \frac{1}{2} ki te hautau me te tautūnga 40.

$$\frac{25}{2}-\left(\frac{67}{40}-\frac{20}{40}\right)-11-\frac{13}{40}$$

Tā te mea he rite te tauraro o \frac{67}{40} me \frac{20}{40}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{25}{2}-\frac{67-20}{40}-11-\frac{13}{40}$$

Tangohia te 20 i te 67, ka 47.

$$\frac{25}{2}-\frac{47}{40}-11-\frac{13}{40}$$

Ko te maha noa iti rawa atu o 2 me 40 ko 40. Me tahuri \frac{25}{2} me \frac{47}{40} ki te hautau me te tautūnga 40.

$$\frac{500}{40}-\frac{47}{40}-11-\frac{13}{40}$$

Tā te mea he rite te tauraro o \frac{500}{40} me \frac{47}{40}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{500-47}{40}-11-\frac{13}{40}$$

Tangohia te 47 i te 500, ka 453.

$$\frac{453}{40}-11-\frac{13}{40}$$

Me tahuri te 11 ki te hautau \frac{440}{40}.

$$\frac{453}{40}-\frac{440}{40}-\frac{13}{40}$$

Tā te mea he rite te tauraro o \frac{453}{40} me \frac{440}{40}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{453-440}{40}-\frac{13}{40}$$

Tangohia te 440 i te 453, ka 13.

$$\frac{13}{40}-\frac{13}{40}$$

Tangohia te \frac{13}{40} i te \frac{13}{40}, ka 0.
