Explanation:

Step1: Translate the description into an expression

First, five times a number $d$ is $5d$. The quotient of $5d$ and ten is $\frac{5d}{10}$. Twice this quotient is $2\times\frac{5d}{10}$.

Step2: Simplify the expression

$2\times\frac{5d}{10}=\frac{10d}{10}=d$.

Answer:

Variable expression: $2\times\frac{5d}{10}$
Simplified expression: $d$
