d. Nonpurchasers to total customers 13:50

4. Ratios as a fraction without reducing.

a. 6: 13 to 6/13

b. 7: 40 to 7/40

10. Normal vision is called 20-20 vision. These numbers are actually a ratio—a comparison of the distance you can see to the distance a normal-sighted person can see. For example, a person with 20-30 vision can see from a distance of 20 feet what a person with 20-20 vision can see from a distance of 30 feet. Based on this knowledge, explain what the following numbers mean regarding vision.

a. 20-100 (a person with 20-100 vision can see from a distance of 20 feet what a person with 20-20 vision can see from a distance of 100 feet.)

b. 20-40 (a person with 20-40 vision can see from a distance of 20 feet what a person with 20-20 vision can see from a distance of 40 feet.)
