Answer
$\frac{1}{10}$
Work Step by Step
Remember, that the product of a number $a$ and its reciprocal is 1. Therefore, the reciprocal of $a$ must be $\frac{1}{a}$ (which is just $a$ flipped), so that $a\times\frac{1}{a}=1$.
Therefore, the reciprocal of 10 is $\frac{1}{10}$.
$10\times\frac{1}{10}=1$
