We want to find a fraction that is between

There are several ways to go about this.
There are also infinitely many fractions that can be found between the given fractions.
Let us go for the one in the middle of the two fractions.
So we add the two fractions and divide by 2.

Answer:
4000
Step-by-step explanation:
To solve :
36 = 0.9% of w ; solve for w
36 = 0.9/100 * w
36 = 0.009w
Divide both sides by 0.009
36/0.009 = 0.009w / 0.009
4000 = w
Hence, the number, w equals 4000
