Note that in mathematics the word 'of ' is interpreted as multiply. Also the letter 'a' (as a word) is interpreted as 1 of ->1xx→1×

color(blue)("Did you mean: in the fraction format of percentage?")
0.004 -=4/1000
But we need the percentage form of this where the denominator is 100.
(4-:10)/(1000-:10) -= 0.4/100
