\frac{140+17}{20}-\frac{4\times 5+1}{5}
Whakareatia te 7 ki te 20, ka 140.
\frac{157}{20}-\frac{4\times 5+1}{5}
Tāpirihia te 140 ki te 17, ka 157.
\frac{157}{20}-\frac{20+1}{5}
Whakareatia te 4 ki te 5, ka 20.
\frac{157}{20}-\frac{21}{5}
Tāpirihia te 20 ki te 1, ka 21.
\frac{157}{20}-\frac{84}{20}
Ko te maha noa iti rawa atu o 20 me 5 ko 20. Me tahuri \frac{157}{20} me \frac{21}{5} ki te hautau me te tautūnga 20.
\frac{157-84}{20}
Tā te mea he rite te tauraro o \frac{157}{20} me \frac{84}{20}, me tango rāua mā te tango i ō raua taurunga.
\frac{73}{20}
Tangohia te 84 i te 157, ka 73.
