Kua tāruatia ki te papatopenga
\frac{16}{3}-\frac{4\times 7+5}{7}
Whakahekea te hautanga \frac{32}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
\frac{16}{3}-\frac{28+5}{7}
Whakareatia te 4 ki te 7, ka 28.
\frac{16}{3}-\frac{33}{7}
Tāpirihia te 28 ki te 5, ka 33.
\frac{112}{21}-\frac{99}{21}
Ko te maha noa iti rawa atu o 3 me 7 ko 21. Me tahuri \frac{16}{3} me \frac{33}{7} ki te hautau me te tautūnga 21.
\frac{112-99}{21}
Tā te mea he rite te tauraro o \frac{112}{21} me \frac{99}{21}, me tango rāua mā te tango i ō raua taurunga.
\frac{13}{21}
Tangohia te 99 i te 112, ka 13.
