Cross multiply then solve for the variable.
u find the common denominator
the figures are similar. Find the value of each variable. solve
To find an unknown value in a proportional relationship, you can set up a ratio equation based on the known values. For example, if you have a proportional relationship expressed as ( \frac{a}{b} = \frac{c}{d} ), where ( a ) and ( b ) are known values, and ( c ) is the unknown, you can cross-multiply to solve for ( c ) by rearranging the equation to ( c = \frac{a \cdot d}{b} ). This allows you to calculate the unknown value while maintaining the proportional relationship.
Take the value of each variable in the expression and replace the variable by its value. Then do the math!
By eliminating or substituting one of the variables in the two equations in order to find the value of the other variable. When this variable is found then substitute its value into the original equations in order to find the value of the other variable.

find the ratio . ratio should be samecheck that if A increases value of B also incresase. if our ques holds both the property it means that it is direct proportional .
Direct proportional means as one value increases the other value increases as well. For example, if add mass into a plastic bag the bag will expand/stretch therefore if mass increase the streching will increase as well. Hope you find it helpful!

The answer will depend on what aspect is the variable.
Take the value of each variable in the expression and replace the variable by its value. Then do the math!
You divide the numerator of the ratio by its denominator.
The variable that depens on a number or anther variable to find it's value.
By eliminating or substituting one of the variables in the two equations in order to find the value of the other variable. When this variable is found then substitute its value into the original equations in order to find the value of the other variable.
Solving for one variable makes it easy to put in a value for the other variables, and find a value for the first variable.
