36 is 0.9% of what number. use percent proportions to solve.
36 is 0.9% of 4,000

Explanation:

Step1: Set up percent proportion

The percent proportion formula is $\frac{\text{part}}{\text{whole}} = \frac{\text{percent}}{100}$. Let the unknown whole number be $x$. Here, part = 36, percent = 0.9.
$\frac{36}{x} = \frac{0.9}{100}$

Step2: Cross-multiply to solve for $x$

Cross-multiply to isolate $x$.
$0.9x = 36 \times 100$

Step3: Calculate right-hand side

Compute the product on the right.
$0.9x = 3600$

Step4: Solve for $x$

Divide both sides by 0.9 to find $x$.
$x = \frac{3600}{0.9} = 4000$

Answer:

4000
