The first number is 20% smaller that the second number
Step-by-step explanation:
Let us revise the percentage of increasing and decreasing
- Increasing% = [(large - small)/small] × 100%
- Decreasing% = [(large - small)/large] × 100%
∵ The two numbers are 20 and 25
∵ 25 is the larger
- Find the percentage of increasing to find the second number
is larger than the first number by what percent
∴ The large number is 25
∴ The small number is 20
∴ Increasing% = × 100%
∴ Increasing% = 25%
∴ The second number is 25% larger than the first number
- Find the percentage of decreasing to find the first number
is smaller than the second number by what percent
∵ Decreasing% = × 100%
∴ Decreasing% = 20%
∴ The first number is 20% smaller than the second number
The second number is 25% larger than the first number
The first number is 20% smaller that the second number
