Explanation:

Question #3

Step1: Calculate the fraction

To find the percentage, first find the fraction of students who play basketball, which is $\frac{7}{35}$.

Step2: Simplify the fraction

Simplify $\frac{7}{35}$ to $\frac{1}{5}$.

Step3: Convert to percentage

To convert $\frac{1}{5}$ to a percentage, multiply by 100: $\frac{1}{5} \times 100 = 20\%$.

Step1: Let the total number of coins be $x$

We know that 50% (or 0.5) of the coins are dimes, and the number of dimes is 30. So we can set up the equation $0.5x = 30$.

Step2: Solve for $x$

To solve for $x$, divide both sides of the equation by 0.5: $x = \frac{30}{0.5} = 60$.

Step1: Calculate the fraction

The fraction of non - fiction books is $\frac{6}{25}$.

Step2: Convert to percentage

Multiply the fraction by 100 to get the percentage: $\frac{6}{25} \times 100 = 24\%$.

Answer:

B. 20%
