Tohaina
Kua tāruatia ki te papatopenga
z=\frac{15}{4}-\frac{5\times 7}{2\times 5}
Me whakarea te \frac{5}{2} ki te \frac{7}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
z=\frac{15}{4}-\frac{7}{2}
Me whakakore tahi te 5 i te taurunga me te tauraro.
z=\frac{15}{4}-\frac{14}{4}
Ko te maha noa iti rawa atu o 4 me 2 ko 4. Me tahuri \frac{15}{4} me \frac{7}{2} ki te hautau me te tautūnga 4.
z=\frac{15-14}{4}
Tā te mea he rite te tauraro o \frac{15}{4} me \frac{14}{4}, me tango rāua mā te tango i ō raua taurunga.
z=\frac{1}{4}
Tangohia te 14 i te 15, ka 1.
