Clare has 5 yards of ribbon. It takes 1/2 yard to make a bow. How many bows can Clare make with the ribbon? Write a multiplication and division equation showing the solution.

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
