12\left(\frac{8}{60}-\frac{21}{60}\right)
Ko te maha noa iti rawa atu o 15 me 20 ko 60. Me tahuri \frac{2}{15} me \frac{7}{20} ki te hautau me te tautūnga 60.
12\times \frac{8-21}{60}
Tā te mea he rite te tauraro o \frac{8}{60} me \frac{21}{60}, me tango rāua mā te tango i ō raua taurunga.
12\left(-\frac{13}{60}\right)
Tangohia te 21 i te 8, ka -13.
\frac{12\left(-13\right)}{60}
Tuhia te 12\left(-\frac{13}{60}\right) hei hautanga kotahi.
\frac{-156}{60}
Whakareatia te 12 ki te -13, ka -156.
-\frac{13}{5}
Whakahekea te hautanga \frac{-156}{60} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 12.
