Imagine you have a delicious pizza cut into 3 equal slices. If you eat 1 slice, you have eaten 1/3 of the pizza. In percentages, this 1/3 is approximately 33.33%. So, eating 1 out of 3 slices is the same as eating 33.33% of the pizza.

Worked Example

Step-by-Step

Let's convert 33.33% to a fraction.

Step 1: Remember that 'percent' means 'out of 100'. So, 33.33% can be written as 33.33/100.
---Step 2: We have a decimal in the numerator. To remove it, multiply both the numerator and denominator by 100. (Because 33.33 has two decimal places).
---Step 3: (33.33 * 100) / (100 * 100) = 3333 / 10000.
---Step 4: Now, we need to simplify this fraction. Notice that 33.33 is very close to 1/3. In fact, 0.3333... is exactly 1/3.
---Step 5: So, if we consider 33.33% as 33 and 1/3 percent, we can write it as (100/3) / 100.
---Step 6: (100/3) / 100 = 100 / (3 * 100) = 100 / 300.
---Step 7: Simplify 100/300 by dividing both numerator and denominator by 100. This gives 1/3.

Answer: So, 33.33% as a fraction is 1/3.
