Identify Total Magazines: Step $1$ : Identify the total number of magazines and the number of women's magazines. $\newline$ Total magazines: $90$ $\newline$ Women's magazines: $81$ $\newline$ We need to calculate the percentage of women's magazines.
Use Percentage Formula: Step $2$ : Use the percentage formula. $\newline$ Percentage = $(\frac{\text{Number of women's magazines}}{\text{Total number of magazines}}) \times 100$ $\newline$ Substitute the values into the formula. $\newline$ Percentage = $(\frac{81}{90}) \times 100$
Perform Division: Step $3$ : Perform the division to simplify. $81 / 90 = 0.9$
Multiply for Percentage: Step $4$ : Multiply by $100$ to find the percentage. $\newline$ $0.9 \times 100 = 90\%$ $\newline$ So, $90\%$ of the magazines at the bookstore are women's magazines.
