Whoever answer this right gets brainleist What is the constant of proportionality in the equation y=\dfrac23xy=
2/3 xy, equals, start fraction, 2, divided by, 3, end fraction, x?
constant of proportionality ==

2 /3

Step-by-step explanation:

This equation demonstrates direct proportionality, as we have the form  y=kx

where  k is the constant of proportionality.

Looking at the equation,  k=2/3 is our constant of poportionality

because that is what we divide by.

Hope this helps :D

thanks

All rational numbers are fractions.

Step-by-step explanation:

A rational number is a type of number that can be expressed as a fraction, a/b where

a is the numerator.

b is the denominator.

b may be equal to 1 so every integer is a rational number

Rational numbers have numerator and denominator.

A set of rational numbers is called "rationals". Example of rational numbers includes 0, 5, 6, 44/5, 12357/68.
