Answer :
Final answer:
To determine the greatest number of 6x4 materials that can be made from a 16x20 material, we need to calculate the area of each piece and divide the total area of the larger material by the area of the smaller material.
Explanation:
- Find the area of the 16x20 material by multiplying the length and width: 16 * 20 = 320 square units.
- Find the area of the 6x4 material by multiplying the length and width: 6 * 4 = 24 square units.
- Divide the area of the 16x20 material by the area of the 6x4 material to find the greatest number: 320 / 24 = 13.33333. Since we can't have a fraction of a piece, we can only make a maximum of 13 6x4 materials out of the 16x20 material.
