![1200 - 1176 = 24](https://tex.z-dn.net/?f=1200%20-%201176%20%3D%2024)
24 is the amount of reduction
![\frac{x}{100} = \frac{24}{1200} \\ x = \frac{24\times 100}{1200} = \frac{2400}{1200} = 2](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B100%7D%20%20%3D%20%20%5Cfrac%7B24%7D%7B1200%7D%20%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B24%5Ctimes%20100%7D%7B1200%7D%20%20%3D%20%20%5Cfrac%7B2400%7D%7B1200%7D%20%20%3D%202)
so the reduction percentage is 2%
