In the concrete the ratio of the mass of saint Simon and Stone is 3.2.5 What Fraction of the concrete Cement
Let the mass of Saint Simon be 3x and the mass of Stone be 5x.
Since the ratio of their masses is 3:5, the total mass of the concrete is 3x + 5x = 8x
Let the mass of cement be y. Since cement is a component of concrete, we have the following equation:
y = 3/8 * (3x) = 9x/8
Therefore, the fraction of the concrete that is cement is 9x/8 / 8x = 9/64.
