Question

If a is directly proportional to b and a =2.4 when b =3, find the relationship between a and b​

Answer 1

Explanation:

a is directly proportional to b

means a = k b

or a/b = k where 'k' is the proportionality constant

when a = 2.4 and b = 3 a/b = k = 2.4/3

so k = .8

a = .8 b is the relationship equation
