\frac{1}{3}-\frac{1}{7}
Whakahekea te hautanga \frac{2}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
\frac{7}{21}-\frac{3}{21}
Ko te maha noa iti rawa atu o 3 me 7 ko 21. Me tahuri \frac{1}{3} me \frac{1}{7} ki te hautau me te tautūnga 21.
\frac{7-3}{21}
Tā te mea he rite te tauraro o \frac{7}{21} me \frac{3}{21}, me tango rāua mā te tango i ō raua taurunga.
\frac{4}{21}
Tangohia te 3 i te 7, ka 4.
