In Equation 3.0, you don't just type the equation: you have to use the templates that are available from the floating Equation Editor toolbar. The second group from the left on the bottom row are "fraction and radical templates." You insert a fraction template (the top left one), and then you get two boxes to type in. You type your numerator in the top one and your denominator in the bottom one.
To insert the multiplication sign (which EE uses instead of *), you select it from the "Operator symbols" gallery (fourth from the left on the top row). EE spaces elements automatically and doesn't accept input from the Spacebar, but if you want more space between elements, you can insert spaces from the "Spaces and ellipses" gallery. Exponents, matrices, and other elements and symbols are available from other galleries on the toolbar.
