Question

evaluate \\(\frac{j}{k} - 0.2k\\) when \\(j = 25\\) and \\(k = 5\\).

Explanation:

Step1: Substitute the values of j and k

Substitute \( j = 25 \) and \( k = 5 \) into the expression \( \frac{j}{k}-0.2k \). So we get \( \frac{25}{5}-0.2\times5 \).

Step2: Calculate each part

First, calculate \( \frac{25}{5}=5 \), and then calculate \( 0.2\times5 = 1 \).

Step3: Subtract the two results

Subtract the second result from the first: \( 5 - 1 = 4 \).
