1-\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.
1-\frac{5+4}{40}
Tā te mea he rite te tauraro o \frac{5}{40} me \frac{4}{40}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
1-\frac{9}{40}
Tāpirihia te 5 ki te 4, ka 9.
\frac{40}{40}-\frac{9}{40}
Me tahuri te 1 ki te hautau \frac{40}{40}.
\frac{40-9}{40}
Tā te mea he rite te tauraro o \frac{40}{40} me \frac{9}{40}, me tango rāua mā te tango i ō raua taurunga.
\frac{31}{40}
Tangohia te 9 i te 40, ka 31.
