Tohaina
Kua tāruatia ki te papatopenga
138\times 10^{-3}\times 54
Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 2 me te -5 kia riro ai te -3.
138\times \frac{1}{1000}\times 54
Tātaihia te 10 mā te pū o -3, kia riro ko \frac{1}{1000}.
\frac{69}{500}\times 54
Whakareatia te 138 ki te \frac{1}{1000}, ka \frac{69}{500}.
\frac{1863}{250}
Whakareatia te \frac{69}{500} ki te 54, ka \frac{1863}{250}.
