To solve the proportion 3.2:5 = x:3.5, we can use cross multiplication.
Cross multiplication involves multiplying the numerator of the first fraction by the denominator of the other fraction and vice versa.
In this case, we have:
(3.2)(3.5) = (5)(x)
11.2 = 5x
To isolate x, divide both sides of the equation by 5:
11.2/5 = x
x ≈ 2.24
So, the value of x in the given proportion is approximately 2.24.
