Solve the proportion: \(127.5 \div 17 = 187.5 \div x\)

Step 1: Rewrite the proportion as a fraction.
\(\frac{\mathrm{127.5} }{\mathrm{17}} = \frac{\mathrm{187.5} }{\mathrm{x}}\)
Step 2: Cross multiply.
\(127.5x=187.5 \times 17\)
Step 3: Simplify the right side of the equation
\(127.5x=3187\)
Step 4: Simplify by dividing both sides of the equation by 127.5.
\(\frac{\mathrm{127.5x} }{\mathrm{127.5}} = \frac{\mathrm{3187.5} }{\mathrm{127.5}}\)
\(x=25\)
