Which equation represents a proportional relationship that has a constant of proportionality equal to 1/5

Option C is correct

y = 1/5 x

Step-by-step explanation:

Option C is correct

Step-by-step explanation:

The Proportional relationship says that:

then

the equation is of the form :

y = kx .....[1] where k is the constant of Proportionality

As per the statement:

Constant of proportionality (k) =

Substitute in [1] we get;

Therefore, an equation represents a proportional  relationship that has a constant of proportionality equal to 1/5 is

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
