5. Solve: 180 is what percent of 125 ? Round to the nearest tenth. $85.6 \%$ $14.4 \%$ $1.44 \%$ $144 \%$

Step 1 ：First, we need to set up the equation. Let's denote the unknown percentage as x. So, we have: \(180 = x\% \times 125\)

Step 2 ：Next, we convert the percentage to a decimal by dividing x by 100: \(180 = \frac{x}{100} \times 125\)

Step 3 ：Then, we solve for x by dividing both sides of the equation by 125: \(x = \frac{180}{125} \times 100\)

Step 4 ：Calculating the right side of the equation gives us: \(x = 144\)

Step 5 ：So, 180 is 144% of 125. Therefore, the answer is \(\boxed{144\%}\)
