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.
To find the constant of proportionality in a table, identify the ratio of the dependent variable to the independent variable for any pair of values; this ratio should remain consistent across all pairs. In a graph, the constant of proportionality is the slope of the line, which represents the change in the dependent variable per unit change in the independent variable. In an equation of the form ( y = kx ), the constant of proportionality is the coefficient ( k ). If the relationship is proportional, ( k ) will be the same regardless of the values chosen.
Take the value of each variable in the expression and replace the variable by its value. Then do the math!

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!

To find an unknown value in a proportional relationship, you can set up a ratio equation based on the known values.

This allows you to calculate the unknown value while maintaining the proportional relationship.
The answer will depend on what aspect is the variable.

To find the missing value in a ratio table, identify the known values that correspond to one another across the rows or columns. Use the concept of equivalent ratios by setting up a proportion, where the known values are placed in a fraction form. Solve for the missing value by cross-multiplying and isolating the variable. Finally, ensure that the resulting value maintains the same ratio as the others in the table.
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.
