Calculate Percentage: Finding Yellow Candles in a Set of 54

Roland counts the candles in the box and discovers that it contains 54 candles, 6 of which are yellow.

What is the percentage of yellow candles?

To solve this problem, we'll determine what percentage of the candles are yellow:

• Step 1: Use the formula for a percentage: $\text{Percentage of yellow candles} = \left( \frac{\text{Number of yellow candles}}{\text{Total number of candles}} \right) \times 100$
• Step 2: Plug in the given numbers: The number of yellow candles is 6, and the total number of candles is 54.
• Step 3: Calculate the fraction and convert to percentage: $\frac{6}{54} \times 100$

Let's calculate:
$\frac{6}{54} = 0.1111\ldots$ (repeating decimal).
Then, convert to a percentage:
$0.1111\ldots \times 100 = 11.11\ldots$ which we round to the nearest whole number, resulting in 11%.

Therefore, 11% of the candles in the box are yellow.
