Question

there were 12 stray cats in a town. one year later, there were 21 stray cats in the town. what was the percent change? ?%

Explanation:

Step1: Find the change in number

The initial number of stray cats is 12, and the final number is 21. The change is $21 - 12 = 9$.

Step2: Calculate percent change

The formula for percent change is $\frac{\text{Change}}{\text{Original}} \times 100\%$. Substituting the values, we get $\frac{9}{12} \times 100\%$. Simplifying $\frac{9}{12}$ gives $\frac{3}{4}$, and $\frac{3}{4} \times 100\% = 75\%$.

Answer:

75
