The problem asks us to find what percentage of 15 is

9. We need to express the answer as a percentage.

2. Solution Steps

To find what percent 9 is of 15, we can set up the following equation:
915=x100\frac{9}{15} = \frac{x}{100}
Where xx is the percentage we are looking for.
To solve for xx, we can multiply both sides of the equation by 100:
x=915×100x = \frac{9}{15} \times 100
First, we can simplify the fraction 915\frac{9}{15} by dividing both the numerator and the denominator by their greatest common divisor, which is 3:
915=9÷315÷3=35\frac{9}{15} = \frac{9 \div 3}{15 \div 3} = \frac{3}{5}
Now, we can substitute this simplified fraction back into the equation for xx:
x=35×100x = \frac{3}{5} \times 100
To calculate the value of xx, we multiply:
x=3×1005=3005x = \frac{3 \times 100}{5} = \frac{300}{5}
Finally, we divide 300 by 5:
x=60x = 60
Therefore, 9 is 60% of
1
5.

3. Final Answer

60%
