\frac{1}{10}-4=12
Whakahekea te hautanga \frac{10}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.
\frac{1}{10}-\frac{40}{10}=12
Me tahuri te 4 ki te hautau \frac{40}{10}.
\frac{1-40}{10}=12
Tā te mea he rite te tauraro o \frac{1}{10} me \frac{40}{10}, me tango rāua mā te tango i ō raua taurunga.
-\frac{39}{10}=12
Tangohia te 40 i te 1, ka -39.
-\frac{39}{10}=\frac{120}{10}
Me tahuri te 12 ki te hautau \frac{120}{10}.
\text{false}
Whakatauritea te -\frac{39}{10} me te \frac{120}{10}.
