Final answer:
To determine what number 36 is 0.9% of, you set up the equation 0.009 * w = 36. Solving for w gives you w = 36 / 0.009, which is 4000. Hence, 36 is 0.9% of 4000.
Step-by-step explanation:
The question relates to finding out what number 36 represents 0.9% of. To solve this, we need to set up a proportion where 0.9% (which is 0.9 over 100 or 0.009 in decimal form) of a number w equals to 36. The equation would be 0.009 * w = 36. To find w, you divide 36 by 0.009.
The calculation will be:
w = 36 / 0.009
w = 4000
Therefore, 36 is 0.9% of 4000.
The 'blank' in the question is the conversion of the percentage to decimal, which is done by dividing by 100. Thus 'blank' is 0.9/100 = 0.009.
