Kua tāruatia ki te papatopenga
126\left(\frac{9}{21}-\frac{5}{21}\right)
Ko te maha noa iti rawa atu o 7 me 21 ko 21. Me tahuri \frac{3}{7} me \frac{5}{21} ki te hautau me te tautūnga 21.
126\times \frac{9-5}{21}
Tā te mea he rite te tauraro o \frac{9}{21} me \frac{5}{21}, me tango rāua mā te tango i ō raua taurunga.
126\times \frac{4}{21}
Tangohia te 5 i te 9, ka 4.
\frac{126\times 4}{21}
Tuhia te 126\times \frac{4}{21} hei hautanga kotahi.
\frac{504}{21}
Whakareatia te 126 ki te 4, ka 504.
24
Whakawehea te 504 ki te 21, kia riro ko 24.
