To divide 3/4 by 1/2 using unit rate proportionality, we can set up a proportion with 3/4 as the numerator and 1/2 as the denominator, and then cross-multiply and solve for the unknown value.
3/4 / 1/2 = X
To solve for X, we can cross-multiply to get:
(3/4) * (2/1) = X * (1/2)
Which simplifies to:
3/2 = X
So 3/4 divided by 1/2 is equal to 3/2.
It's important to note that when dividing fractions, we can also simply invert the divisor and multiply the two fractions, 3/4 * 2/1 = 6/4 =3/2.
