Kua tāruatia ki te papatopenga
\frac{4}{7}-\left(-\frac{5}{3}\right)
Ka taea te hautanga \frac{-5}{3} te tuhi anō ko -\frac{5}{3} mā te tango i te tohu tōraro.
\frac{4}{7}+\frac{5}{3}
Ko te tauaro o -\frac{5}{3} ko \frac{5}{3}.
\frac{12}{21}+\frac{35}{21}
Ko te maha noa iti rawa atu o 7 me 3 ko 21. Me tahuri \frac{4}{7} me \frac{5}{3} ki te hautau me te tautūnga 21.
\frac{12+35}{21}
Tā te mea he rite te tauraro o \frac{12}{21} me \frac{35}{21}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{47}{21}
Tāpirihia te 12 ki te 35, ka 47.
