Answer:
16
Step-by-step explanation:
First, you can create a ratio:
Number of people/percentage of total
So 9 being 55% of the painting crew would be:
[tex]\frac{9}{0.55}[/tex], because we are trying to find the total number of painters, you can create another fraction where x is the numerator (number of people) and the denominator is 1 (or 100% of the painters). [tex]\frac{x}{1}[/tex]
Because these fractions are proportions of the same thing, we can set them equal to each other.
[tex]\frac{9}{0.55} =\frac{x}{1}[/tex], cross multiplying gives:
9=0.55x
Dividing both sides by 0.55 gives:
x=(around) 16
