Two methods:

  1. work out 49% of 940 and subtract it from 940; or
  2. see that what will be left will be 100% - 49% = 51% of 940, so work out 51% of 940.

That's how I decrease 940 by 49 percent. This is me actually doing it:

"percent" means "out of 100", so 49% means 49/100, thus

49% of 940 is 49/100 x 940 = 4603/5

So decreasing 940 by 49% is 940 - 4603/5 = 4792/5 = 479.4

Alternatively:

decreasing by 49% is the same as working out 100% - 49% = 51%. so

51% of 940 is 51/100 x 940 = 4792/5 = 479.4
