What is 10% of 40?To calculate the percent of any number, we will first learn about or get familiar with the concept of percentages. So, in this article, we will learn basic information about percentages and how to calculate any number's Percentage. PercentageThe word Percentage combines two Latin words: "Per" and "Centum"; both words have different meanings. The word Centrum has the meaning which is "Hundred," and the word "Per" has the meaning "by." So, combining these, we can say that the word has a meaning, i.e., by a hundredth. So, using this, the definition of Percentage can be defined as the value of something that is compared with the hundredth of its value. Remember that we calculated our overall marks out of our total marks as students. There we used the word Percentage; we used, to sum up all the marks we got in our particular subjects, divide them by the total marks of subjects, and then multiply the result by hundred (100). For Example: Let us consider that we got 80 marks in Hindi out of 100, 93 marks in Mathematics out of 100, 84 marks in English out of 100, 95 marks in Science out of 100, and 92 marks in Physical Education out of 100. When we sum up all the marks of each subject, we get 444, divide it by 500, the total marks, and multiply it by 100 to get the marks percentage. (444/ 500) * 100 = 88.8 % So that child got 88.8 % in his examination. What is the Actual Meaning of 10% of 40?In particular, 10% of 40 is 4. We can understand this concept by simply assuming 40 as 100 equal parts and objects and can assume anything; then 10 parts or objects from those 100 equal parts are considered 10%; for our case, 4 is the answer. Steps to Calculate 10% of 40We will learn how to calculate 10% of 40 with the help of some simple steps, which are explained in the following lines. Step 1. First, write the product of both numbers, i.e., 10% and 40, as shown below. 10% * 40 Step 2. As we know, the meaning of Percentage is the 100^{th} part of a number or anything, so that we can replace the percentage "%" sign with (1 / 100). Implies 10% * 40 = (10 / 100) *40 Step 3. Using the rules of multiplication and simplification, we get the following: = 10% * 40 = (10 / 100) *40 = 400 / 100 = 4 Suppose the pie chart represents 40 values. To determine 10% of 40, we calculate 4. The chart section occupied by the 4 values represents 10% of the total. The remaining portion of the chart represents 90% of the 40 values. Since 40 is the total value, the entire pie chart represents 100% of it. Applications of PercentagePercentages are used in various fields of Mathematics and many other fields, including the following:
Some Solved Examples1. What is 150% of 100? Solution: Step 1. 150% * 100 Step 2. 150% * 100 = (150 / 100) * 100 Step 3. 150% * 100 = (150 / 100) * 100 = 150 2. What is 15% of 15? Solution: Step 1. 15% * 15 Step 2. 15% * 15 = (15 / 100) * 15 Step 3. 50% * 100 = (15 / 100) * 15 = 225 / 100 = 2.25 3. What is 75% of 60? Solution: Step 1. 75% * 60 Step 2. 75% * 60 = (75 / 100) * 60 Step 3. 75% * 60 = (75 / 100) * 60 = 45 ConclusionUnderstanding percentages is an important math skill that finds applications in various fields and realworld situations. In our case of calculating 10% of 40, we multiply the total value by 10% (0.10) to obtain the result, i.e., 40. By understanding percentages, we can improve our problemsolving abilities and make informed decisions in various aspects of life.
