What are Percentages?
A percentage is a way of representing a part of a whole as a fraction of 100. The symbol “%” signifies “out of one hundred.” For instance, 50% means 50 out of every 100, or half. Percentages are often used to express proportions, ratios, and changes in quantities.
Calculating Percentages
To calculate a percentage, follow these steps:
- Divide the part by the whole.
- Multiply the result by 100.
For example, if you want to find what percentage 20 is of 100, you would:
1. Divide 20 by 100: 20 / 100 = 0.20 (See Also: Are Math Teachers in Demand? Future of Education)
2. Multiply 0.20 by 100: 0.20 * 100 = 20%
Solving “38 is What Percent of 104?”
Now, let’s apply this knowledge to our specific question: “38 is what percent of 104?”
Here, 38 represents the part, and 104 represents the whole. Following the steps outlined above:
- Divide the part by the whole: 38 / 104 = 0.3654 (rounded to four decimal places)
- Multiply the result by 100: 0.3654 * 100 = 36.54%
Therefore, 38 is 36.54% of 104.
