Tohaina
Kua tāruatia ki te papatopenga
n+\frac{1}{5}=0.0021
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
n=0.0021-\frac{1}{5}
Tangohia te \frac{1}{5} mai i ngā taha e rua.
n=\frac{21}{10000}-\frac{1}{5}
Me tahuri ki tau ā-ira 0.0021 ki te hautau \frac{21}{10000}.
n=\frac{21}{10000}-\frac{2000}{10000}
Ko te maha noa iti rawa atu o 10000 me 5 ko 10000. Me tahuri \frac{21}{10000} me \frac{1}{5} ki te hautau me te tautūnga 10000.
n=\frac{21-2000}{10000}
Tā te mea he rite te tauraro o \frac{21}{10000} me \frac{2000}{10000}, me tango rāua mā te tango i ō raua taurunga.
n=-\frac{1979}{10000}
Tangohia te 2000 i te 21, ka -1979.
