Question

Percent increase and decrease. Original number:45 New number: 18

Answer 1

Answer:

60% decrease

Step-by-step explanation:

To find the percentage increase/ decrease construct a fraction with numerator showing increase/ decrease and denominator with original number then multiply the fraction by 100%

here the decrease = 45 - 18 = 27

percent decrease = $\frac{decrease}{original}$ × 100%

                             = $\frac{27}{45}$ × 100% = 60%
