Question

the following table shows a proportional relationship between a and b . write an equation to describe the relationship between a and b

Answer 1

The rule of given table is (a÷2)-(b÷3).

Step-by-step explanation:

From the given table it is clear that

8 becomes 3

24 becomes 9

40 becomes 15

Rule

(8÷2)-(3÷3) = (4-1) = 3

(24÷2)-(9÷3) = (12-3) = 9

(40÷2)-(15÷3) = (20-5) = 15

So, the equation will be

(a÷2)-(b÷3)

Answer 2

Answer is b= (3/8)a this is verified, but can't explain why.
