Calculating the Percentage
To calculate what percentage 7 is of 28, we need to divide 7 by 28 and then multiply the answer by 100. First, divide 7 by 28: 7 ÷ 28 = 0.25. Next, multiply that answer by 100: 0.25 x 100 = 25. This means that 7 is 25% of 28.
It is important to remember that percentages are a way of expressing a ratio as a fraction of 100. In other words, when we say that 7 is 25% of 28, we mean that the ratio between 7 and 28 is 1:4 (or 1/4).
We can also calculate percentages using proportions. To do this, cross-multiply the two numbers in the ratio (7 and 28). When we cross-multiply these two numbers, we get: 7 x 100 = 28 x p, where p is the percentage we are looking for. Therefore, if we solve for p, we get: p = 25%. This means that 7 is 25% of 28.
Knowing how to calculate percentages can be a helpful tool in many real-world situations. For example, if you want to find out what percentage of your salary will go towards taxes each month, you can use this method to calculate it quickly and easily!
