20% Of What Number Is 12
In daily life, we often come across situations where we need to calculate percentages. Whether it’s calculating discounts, interest rates, or determining proportions, percentages play a crucial role. One common question that arises is, “What number is 20% of 12?” In this article, we will explore how to find the answer to this question, as well as provide some frequently asked questions related to percentages.
Calculating 20% of a number is a straightforward process. To find out what number is 20% of 12, we need to apply a simple formula:
(Number × Percentage) ÷ 100 = Result
In this case, the number we want to find is represented by “X,” and the percentage is 20%. Plugging in these values, we get:
(X × 20) ÷ 100 = 12
Simplifying the equation, we have:
X/5 = 12
To isolate X, we need to multiply both sides of the equation by 5:
(X/5) × 5 = 12 × 5
X = 60
Hence, 20% of 60 is equal to 12.
