FIND THE CONSTANT OF PROPORTIONALITY FROM A TABLE

About "Find the constant of proportionality from a table"

Find the constant of proportionality from a table :

Two variables have a proportional relationship if the ratio of one variable to the other is constant.

If x and y have a proportional relationship, the constant of proportionality is the ratio of y to x.

Let us see some example problems based on the above concept.

Example 1 :

Determine the constant of proportionality for each table.

Solution :

To find the constant of proportionality, we have to divide y by x.

Ratio of y to x :

(i) 30/3  =  10

(ii) 80/8  =  10

(iii) 100/10  =  10

(iv) 60/6  =  10

(v) 70/7  =  10

The ratio for each pair of x- and y-values is 10. So, the variables have a proportional relationship.

Every concrete block weighs 10 kilograms.

Example 2 :

Determine the constant of proportionality for each table.

Solution :

To find the constant of proportionality, we have to divide y by x.

Ratio of y to x :

(i) 15/5  =  3

(ii) 30/10  =  3

(iii) 18/6  =  3

(iv) 27/9  =  3

(v) 6/2  =  3

The ratio for each pair of x- and y-values is 3. So, the variables have a proportional relationship.

For every can of paint you could paint 3 bird houses.

Example 3 :

Determine the constant of proportionality for each table.

Solution :

To find the constant of proportionality, we have to divide y by x.

Ratio of y to x :

(i) 342/9  =  38

(ii) 266/7  =  38

(iii) 228/6  =  38

(iv) 304/8  =  38

(v) 114/3  =  38

The ratio for each pair of x- and y-values is 38. So, the variables have a proportional relationship.

For Every vote for Faye there were 38 votes for Victor.

Example 4 :

Determine the constant of proportionality for each table.

Solution :

To find the constant of proportionality, we have to divide y by x.

Ratio of y to x :

(i) 1212/6  =  202

(ii) 808/4  =  202

(iii) 2020/10  =  202

(iv) 606/3  =  202

(v) 1616/8  =  202

The ratio for each pair of x- and y-values is 202. So, the variables have a proportional relationship.

Every chocolate bar has 202 calories.

Example 5 :

Determine the constant of proportionality for each table.

Solution :

To find the constant of proportionality, we have to divide y by x.

Ratio of y to x :

(i) 14/7  =  2

(ii) 16/8  =  2

(iii) 12/6  =  2

(iv) 20/10  =  2

(v) 4/2  =  2

The ratio for each pair of x- and y-values is 2. So, the variables have a proportional relationship.

For each piece of chicken it costs 2 dollars.

Example 6 :

Determine the constant of proportionality for each table.

Solution :

To find the constant of proportionality, we have to divide y by x.

Ratio of y to x :

(i) 32/2  =  16

(ii) 80/5  =  16

(iii) 144/9  =  16

(iv) 112/7  =  16

(v) 160/10  =  16

The ratio for each pair of x- and y-values is 16. So, the variables have a proportional relationship.

For every box of candy you get 16 pieces.
