Answer:
200,000
Step-by-step explanation:
To find how many times smaller is smaller number than greater number, divide greater number by smaller number.
Greater number [tex]=4\times 10^{-5}[/tex]
Smaller number [tex]=2\times 10^{-10}[/tex]
Then
[tex]\dfrac{\text{Greater number}}{\text{Smaller number}}\\ \\=\dfrac{4\times 10^{-5}}{2\times 10^{-10}}\\ \\=\dfrac{4}{2}\times \dfrac{10^{-5}}{10^{-10}}\\ \\=2\times \dfrac{1}{10^{-5}}\\ \\=2\times 10^5\\ \\=2\times 100,000\\ \\=200,000[/tex]
