Kua tāruatia ki te papatopenga
x=\frac{7}{5}-\frac{5}{8}
Tangohia te \frac{5}{8} mai i ngā taha e rua.
x=\frac{56}{40}-\frac{25}{40}
Ko te maha noa iti rawa atu o 5 me 8 ko 40. Me tahuri \frac{7}{5} me \frac{5}{8} ki te hautau me te tautūnga 40.
x=\frac{56-25}{40}
Tā te mea he rite te tauraro o \frac{56}{40} me \frac{25}{40}, me tango rāua mā te tango i ō raua taurunga.
x=\frac{31}{40}
Tangohia te 25 i te 56, ka 31.
