What does solve a proportion mean?

To solve a proportion means to find the value of a variable that makes two ratiOS equal to each other. A proportion is typically expressed as an equation of the form ( \frac{a}{b} = \frac{c}{d} ). To solve it, you can cross-multiply (i.e., ( a \times d = b \times c )) and then isolate the variable to find its value. This process helps determine unknown quantities in various mathematical and real-world contexts.
