It is: 20% of 1875 = 375.
20% can be written as 0.2, if you meant 45 - 0.2 that equals 44.8 If you meant 45 minus 20 percent of 45, then 45-(45 x 0.2) equals 36

x2 - x = 20 x = 5
You would do 540 x .10 and this would give you 10% of that number, which equals 54. .10 = 10% .20 = 20%

54 x (1 - (20/100)) = 54 x 0.8 = 43.2

It is: 20% of 1875 = 375.
35 - 20% = 35 x (1 - 20/100) = 35 x 0.8 = 28
