What multiplier would you use to find each of these percentage decreases?

1. 10%
2. 30%
3. 5%
4. 85%

1 answer

To find the multiplier for a percentage decrease, you can subtract the percentage from 100 and then divide by 100. Let's calculate the multipliers for each percentage decrease:

1. For a 10% decrease:
Multiplier = (100 - 10) / 100 = 0.9

2. For a 30% decrease:
Multiplier = (100 - 30) / 100 = 0.7

3. For a 5% decrease:
Multiplier = (100 - 5) / 100 = 0.95

4. For an 85% decrease:
Multiplier = (100 - 85) / 100 = 0.15
