Answer
$=0.00000000689$
$=\frac{689}{100000000000}$
$=\frac{689}{10^{11}}$
$=689\times10^{-11}$
$=6.89\times100\times10^{-11}$
$=6.89\times10^2\times10^{-11}$
$=6.89\times10^{-9}$
$=\frac{689}{100000000000}$
$=\frac{689}{10^{11}}$
$=689\times10^{-11}$
$=6.89\times100\times10^{-11}$
$=6.89\times10^2\times10^{-11}$
$=6.89\times10^{-9}$
