Question

1. you answer 21 out of 25 questions correctly on a test. do you reach your goal of answering at least 80% of the questions correctly?

Explanation:

Step1: Calculate the percentage

To find the percentage of correct answers, we use the formula: $\text{Percentage} = \frac{\text{Number of correct answers}}{\text{Total number of questions}} \times 100\%$. Substituting the values, we get $\frac{21}{25} \times 100\%$.

Step2: Simplify the fraction

$\frac{21}{25} = 0.84$, and $0.84 \times 100\% = 84\%$.

Step3: Compare with the goal

The goal is at least $80\%$. Since $84\% > 80\%$, we reach the goal.

Answer:

Yes, because the percentage of correct answers is $84\%$ which is greater than $80\%$.
