The property of proportions states that two ratios are equal, and this property can be used to solve for unknown values in a proportional relationship.
Here is an example: Let's say that 5 apples cost $2.50. We can express this relationship as a ratio:
5 apples / $2.50 = x apples / $5.00
Using the property of proportions, we can cross-multiply and solve for x:
5 apples x $5.00 = $2.50 x x apples
25 = $2.50x
x = 10
Therefore, 10 apples would cost $5.00, and we were able to solve for this unknown value using the properties of proportions.
