Kua tāruatia ki te papatopenga
\frac{3\times 25+4}{25\times 100}-1
Tuhia te \frac{\frac{3\times 25+4}{25}}{100} hei hautanga kotahi.
\frac{75+4}{25\times 100}-1
Whakareatia te 3 ki te 25, ka 75.
\frac{79}{25\times 100}-1
Tāpirihia te 75 ki te 4, ka 79.
\frac{79}{2500}-1
Whakareatia te 25 ki te 100, ka 2500.
\frac{79}{2500}-\frac{2500}{2500}
Me tahuri te 1 ki te hautau \frac{2500}{2500}.
\frac{79-2500}{2500}
Tā te mea he rite te tauraro o \frac{79}{2500} me \frac{2500}{2500}, me tango rāua mā te tango i ō raua taurunga.
-\frac{2421}{2500}
Tangohia te 2500 i te 79, ka -2421.
