75% = 75/100, now find an equivalent ratio with 40 pounds of trash.

Question

| Recyclable materials (lb) | 75 | ?? |
| Trash (lb) | 100 | 40 |

Answer 1

To find the equivalent ratio for 40 pounds of trash, we can set up a proportion using the given ratio of 75%:

75/100 = x/40

Cross multiplying, we get:

100x = 75 * 40
100x = 3000
x = 3000/100
x = 30

Therefore, the equivalent ratio for 40 pounds of trash is 30 pounds of recyclable materials.

| Recyclable materials (lb) | 75 | 30 |
| Trash (lb) | 100 | 40 |
