$$2 \times { 10 }^{ -7 } \times \frac{ 1 }{ 1.9 \times { 10 }^{ -2 } }$$

Aromātai

$$\frac{1}{95000}\approx 0.000010526$$

Ngā Upane Otinga

Tātaihia te 10 mā te pū o -7, kia riro ko \frac{1}{10000000}.

$$2\times \frac{1}{10000000}\times \frac{1}{1.9\times 10^{-2}}$$

Whakareatia te 2 ki te \frac{1}{10000000}, ka \frac{1}{5000000}.

$$\frac{1}{5000000}\times \frac{1}{1.9\times 10^{-2}}$$

Tātaihia te 10 mā te pū o -2, kia riro ko \frac{1}{100}.

$$\frac{1}{5000000}\times \frac{1}{1.9\times \frac{1}{100}}$$

Whakareatia te 1.9 ki te \frac{1}{100}, ka \frac{19}{1000}.

$$\frac{1}{5000000}\times \frac{1}{\frac{19}{1000}}$$

Whakawehe 1 ki te \frac{19}{1000} mā te whakarea 1 ki te tau huripoki o \frac{19}{1000}.

$$\frac{1}{5000000}\times 1\times \frac{1000}{19}$$

Whakareatia te 1 ki te \frac{1000}{19}, ka \frac{1000}{19}.

$$\frac{1}{5000000}\times \frac{1000}{19}$$

Whakareatia te \frac{1}{5000000} ki te \frac{1000}{19}, ka \frac{1}{95000}.

$$\frac{1}{95000}$$

Tauwehe

$$\frac{1}{19 \cdot 2 ^ {3} \cdot 5 ^ {4}} = 1.0526315789473684 \times 10^{-5}$$
