Tohaina
Kua tāruatia ki te papatopenga
2.1\times \frac{1}{100}-2.8\times 10^{-5}
Tātaihia te 10 mā te pū o -2, kia riro ko \frac{1}{100}.
\frac{21}{1000}-2.8\times 10^{-5}
Whakareatia te 2.1 ki te \frac{1}{100}, ka \frac{21}{1000}.
\frac{21}{1000}-2.8\times \frac{1}{100000}
Tātaihia te 10 mā te pū o -5, kia riro ko \frac{1}{100000}.
\frac{21}{1000}-\frac{7}{250000}
Whakareatia te 2.8 ki te \frac{1}{100000}, ka \frac{7}{250000}.
\frac{5243}{250000}
Tangohia te \frac{7}{250000} i te \frac{21}{1000}, ka \frac{5243}{250000}.
