X:5=7:½

To solve the proportion \( \frac{x}{5} = \frac{7}{\frac{1}{2}} \), we can first simplify the right side. \[ \frac{7}{\frac{1}{2}} = 7 \times 2 = 14 \] Now we have: \[ \frac{x}{5} = 14 \] Next, we can solve for \( x \) by multiplying both sides by 5: \[ x = 14 \times 5 \] Calculating that gives: \[ x = 70 \] So, the solution is \( x = 70 \).
