# Explanation:<br /><br />## Step1: <br />Identify the whole and the percent. In this case, the whole is 140 and the percent is 5%.<br /><br />## Step2: <br />Let \( n \) represent the part we are trying to find. <br /><br />## Step3: <br />Write a proportion to solve for \( n \). The proportion is \( \frac { n } { 140 } = \frac { 5 } { 100 } \).<br /><br />## Step4: <br />Cross multiply to solve for \( n \). This gives us \( 100n = 5 \times 140 \).<br /><br />## Step5: <br />Simplify the right side of the equation to get \( 100n = 700 \).<br /><br />## Step6: <br />Divide both sides of the equation by 100 to solve for \( n \). This gives us \( n = 700 \div 100 \).<br /><br />## Step7: <br />Simplify to find the value of \( n \). This gives us \( n = 7 \).<br /><br />### The formula used here is: \( \frac { \text { part } } { \text { whole } } = \frac { \text { percent } } { 100 } \)<br /><br /># Answer: 7<br /><br />Alternatively, you could also find the answer by writing and solving an equation:<br /><br />## Step1: <br />The equation is \( n = 5\% \times 140 \).<br /><br />## Step2: <br />Convert the percent to a decimal to get \( n = 0.05 \times 140 \).<br /><br />## Step3: <br />Multiply to find the value of \( n \). This gives us \( n = 7 \).<br /><br /># Answer: 7
