    Multiply both sides by c to get x = (b/z)*c = bc/z. You can also cross multiply to get xz = bc, then divide by z to get the same answer.

    Look at the rectangle at right. Find the ratio of the shaded area to the area of the whole figure. Find the ratio of the shaded area to the unshaded area.

    Well, the rectangle has a length of 8 units and a width of 4 units, so the area of the whole figure is 8*4 = 32 square units. 12 out of the 32 squares are shaded, and 20 are unshaded. So, (shaded area):(whole figure) = 12/30 = 2/5 and (shaded area):(unshaded area) = 12/20 = 3/5
