Question

A refrigerator magnet uses 5/8 inch of magnetic tape. How many refrigerator magnets can you make with 10 inches of magnetic tape? Explain.

Answer 1

You can make 16 refrigerator magnets. If you divide 10 by 5/8, you multiply by the reciprocal of 5/8 which is 8/5. You have 8/5 x 10. Cross simplify and you have 16.

Answer 2

16 magnet tapes

Explanation:

Length of each refrigerator magnet=
`(5)/(8)` of magnetic tape

Total length of refrigerator = 10 inches

Number of refrigerator magnets=
`( length of magnetic tape)/(length of refrigerator magnet)`

Number of refrigerator magnet=
`(10)/((5)/(8) )`

Number of refrigerator magnet= 10×
`(8)/(5)`

Number of refrigerator magnets= 16 magnet tapes.

Hence, the correct answer is 16 magnetic tapes.
