Question

The following table shows a proportional relationship between j and m.

j m
4 3
12 9
20 15
Write an equation to describe the relationship between j and m.

Answer 1

M = ¾J

If you look at the numbers M is always 3/4 of J so the equation is M = ¾J

Answer 2

Answer: The equation shows the relationship between j and m is given by

`3j=4m`

Explanation:

Since we have given that

j m

4 3

12 9

20 15

Since we have given that there is proportional relationship between j and m.

`(j)/(m)=(4)/(3)\\\\3j=4m`

Hence, the equation shows the relationship between j and m is given by

`3j=4m`
