Kua tāruatia ki te papatopenga
\frac{20+1}{4}-\frac{2\times 5+2}{5}
Whakareatia te 5 ki te 4, ka 20.
\frac{21}{4}-\frac{2\times 5+2}{5}
Tāpirihia te 20 ki te 1, ka 21.
\frac{21}{4}-\frac{10+2}{5}
Whakareatia te 2 ki te 5, ka 10.
\frac{21}{4}-\frac{12}{5}
Tāpirihia te 10 ki te 2, ka 12.
\frac{105}{20}-\frac{48}{20}
Ko te maha noa iti rawa atu o 4 me 5 ko 20. Me tahuri \frac{21}{4} me \frac{12}{5} ki te hautau me te tautūnga 20.
\frac{105-48}{20}
Tā te mea he rite te tauraro o \frac{105}{20} me \frac{48}{20}, me tango rāua mā te tango i ō raua taurunga.
\frac{57}{20}
Tangohia te 48 i te 105, ka 57.
