Kua tāruatia ki te papatopenga
640\left(\frac{5}{40}-\frac{4}{40}\right)
Ko te maha noa iti rawa atu o 8 me 10 ko 40. Me tahuri \frac{1}{8} me \frac{1}{10} ki te hautau me te tautūnga 40.
640\times \frac{5-4}{40}
Tā te mea he rite te tauraro o \frac{5}{40} me \frac{4}{40}, me tango rāua mā te tango i ō raua taurunga.
640\times \frac{1}{40}
Tangohia te 4 i te 5, ka 1.
\frac{640}{40}
Whakareatia te 640 ki te \frac{1}{40}, ka \frac{640}{40}.
16
Whakawehea te 640 ki te 40, kia riro ko 16.
