\frac{1}{2}-\frac{120}{100}
Whakahekea te hautanga \frac{50}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 50.
\frac{1}{2}-\frac{6}{5}
Whakahekea te hautanga \frac{120}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
\frac{5}{10}-\frac{12}{10}
Ko te maha noa iti rawa atu o 2 me 5 ko 10. Me tahuri \frac{1}{2} me \frac{6}{5} ki te hautau me te tautūnga 10.
\frac{5-12}{10}
Tā te mea he rite te tauraro o \frac{5}{10} me \frac{12}{10}, me tango rāua mā te tango i ō raua taurunga.
-\frac{7}{10}
Tangohia te 12 i te 5, ka -7.
