To determine what percentage 45 represents of 135, you can use the formula for calculating a percentage. The formula is:

\[

\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100

\]

In this case, the "Part" is 45 and the "Whole" is 135. Plugging these values into the formula gives:

\[

\text{Percentage} = \left( \frac{45}{135} \right) \times 100

\]

First, simplify the fraction \( \frac{45}{135} \). Both numbers can be divided by 45:

\[

\frac{45}{135} = \frac{1}{3}

\]

Next, convert this fraction into a percentage:

\[

\frac{1}{3} \approx 0.3333

\]

Now, multiply by 100 to convert it into a percentage:

\[

0.3333 \times 100 = 33.33\%

\]

Rounding this to the nearest whole number gives approximately 33%, which corresponds with the answer option indicating 33%. Thus, the reasoning confirms that 45 is
