What is the quotient obtained by subtracting two fifths from the difference between two and three fifths


(2-3 / 5) / (2 / 5)



If a and 0.1 are reciprocal, then a is equal to, and the reciprocal of a is a process


∵ 5 / A and 0.1 are reciprocal, 0.1 = 1 / 10, ∵ A / 5 = 10, a = 50 ∵ A's reciprocal is 1 / 50
