Question

Paul is painting one of the walls because he wants his room to be more colorful. He divides the wall into 9 equal parts and paints one part of the wall green.
What fraction of the wall does he paint green?

• A. $\frac{9}{1}$
• B. $\frac{1}{9}$
• C. $\frac{1}{10}$
  
• D. $\frac{10}{1}$
  

Answer 1

The correct option is B $\frac{1}{9}$


The wall is the whole.
Paul divides the wall into 9 equal parts. The denominator of the fraction is 9.

Paul paints 1 section with green. The numerator of the fraction is 1.

Paul paints one section of the wall green for a total of nine parts.
We can say,
$\text{Paul paints}\frac{1}{9}\text{part of the wall with green}$
