Understanding the Problem

When we are asked to find a percentage, we are essentially being asked to find a fraction of a whole. In this case, we want to find what percentage 39 is of $99. To do this, we need to divide 39 by 99 and then multiply the result by 100 to get the percentage.

Calculating the Percentage

To calculate the percentage, we can use the following formula:

Percentage = (Part / Whole) x 100

In this case, the part is 39 and the whole is 99. So, we can plug these values into the formula:

Percentage = (39 / 99) x 100

Simplifying the Fraction

Before we can calculate the percentage, we need to simplify the fraction 39/99. To do this, we can look for any common factors between the numerator and the denominator. In this case, both 39 and 99 are divisible by 3.

39 ÷ 3 = 13 99 ÷ 3 = 33

So, we can simplify the fraction as follows:

39/99 = 13/33

Calculating the Percentage

Now that we have simplified the fraction, we can plug the values into the formula:

Percentage = (13 / 33) x 100

To calculate the percentage, we can divide 13 by 33 and then multiply the result by 100:

13 ÷ 33 = 0.393939... 0.393939... x 100 = 39.3939...

Rounding the Answer

Since we are looking for a percentage, we can round the answer to two decimal places:

39.39%

Conclusion

Therefore, 39 is approximately 39.39% of $99.
