Question

Write 10−9 as an equivalent fraction.(1 point) 10−9 =

Answer 1

To express \(10^{-9}\) as an equivalent fraction, we can rewrite it using the definition of negative exponents.

\[
10^{-9} = \frac{1}{10^9}
\]

Thus, \(10^{-9}\) as an equivalent fraction is:

\[
\frac{1}{10^9}
\]

If you want to express \(10^9\) in decimal form as well:

\[
10^9 = 1000000000
\]

So, you can also write:

\[
10^{-9} = \frac{1}{1000000000}
\]

Therefore, the equivalent fraction for \(10^{-9}\) is \(\frac{1}{10^9}\) or \(\frac{1}{1000000000}\).
