Answer :
Approximatley 4.39. If thought of like .33X=1.45, then you just divide 1.45 by .33
Answer is 4.39.
Explanation;
Let's assume the number is "Y".
The problem says 33% of Y is equal to 1.45. We can express this in a simple equation as
Y x (33/100) = 1.45
By solving the equation we can find the value as
Y = (1.45 x 100) / 33
Y = 4.39
