Understand the problem: Understand the problem. $\newline$ We need to find the value of $d$ such that $5$ is $d\%$ of $8$ . This means we need to find a number $d$ such that when we take $d$ percent of $8$ , we get $5$ .
Set up the equation: Set up the equation. $\newline$ $d\%$ of $8$ is equal to $5$ . In mathematical terms, this can be written as $(d/100) \times 8 = 5$ .
Solve for d: Solve for d. $\newline$ To find d, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by $8$ . $\newline$ $\frac{d}{100} \times 8 = 5$ $\newline$ $\frac{d}{100} = \frac{5}{8}$
Calculate the value of d: Calculate the value of d. $\newline$ Now we multiply both sides of the equation by $100$ to get $d$ by itself. $\newline$ $d = (\frac{5}{8}) \times 100$ $\newline$ $d = 0.625 \times 100$ $\newline$ $d = 62.5$
