Fractions, Decimals, And Percentages When To Use Each?

Must read

Children need to have a firm grasp of the applications of fractions, decimals, and percentages. Decimals, percentages, and fractions are alternative representations of the same value; hence, none should cause any concern.

Children must learn how to work with fractions, decimals, and percentages to succeed in the future workplace. There is no need for alarm because the same quantity can be expressed in various formats, including decimals, fractions, and shares.

An introduction to fractions, decimals, and Percentages Can Be Beneficial to young children.

In Other Words, What Do Percentages Represent?

A long list of mathematical operations may be used to find answers to problems, including addition, subtraction, multiplication, division, etc. The percentage is one such operation that often appears in many mathematical contexts. Is there a chance you could describe it? So, have no fear! What is the exact proportion, anyway?

 Percentage originates from the Latin per centum, which also means “per hundred.” Percentages are fractions written as a decimal fraction of 100. The % sign indicates percentages. A percentage is calculated by dividing a value by 100. The 60/100 and 40/100 equal 60% and 40%, respectively. Any decimal or fraction may be transformed into a percentage by multiplying by 100 and then adding the % sign. As an illustration, if you multiply 0.28 by 100, you get 28 percent.

Fractions

Language is more important than arithmetic when it comes to comprehending fractions. Wholes are the starting point for constructing particles. Several frequent idioms describe sections of a whole, such as “a quarter of a tank of petrol” or “half a cup of tea.” On the other hand, mathematical fractions make use of numbers to represent proportions approximatively.

It is also likely to use the word “one out of four,” where “one” refers to a fraction and “four” refers to the complete. Because the product is a whole number when employed as a multiple of 4, there is no longer a fractional component in the calculation.

Even if the bulk of the functions linked with fractions relies on language, it is still vital to have a solid grasp of mathematics’s part in the process.

Fraction Calculation

If you need to combine 2/3 cup of honey, 1/4 cup of milk, and 1/2 cup of water, but the mixing bowl you’re using can only hold 2 cups; you might want to rethink the proportions of the components used in the recipe.

When you start adding fractions for the first time, you must figure out the scale for your calculations. Consequently, the only thing that needs to be done to bring the percentage up to 3/4 is to add one more to the previously existing 1/2 and 1/4 of the total. On the other hand, adding 3/4 to 2/3 is a complicated calculation. If you cannot devise a more effective solution, you will need to search for a component that can house either three or four persons.

Nevertheless, that number is 12, and both fractions share it.

At this point, you are required to identify the two fractions. After transferring your attention from thirds and quarters, the following step moves on to twelfths as the next level.

The expression seventeen twelfths, written as 17/12, represents the sum of nine and eight twelfths when put together. If you divide 12 by 17, you will obtain 5/12; this is the suitable fraction that will fit into the bowl since the maximum number is less than the bottom digit.

Decimals

Decimals are the most precise technique to determine a fraction of a number. The decimal point indicates that the digit to its right is a fraction of the whole. Example: the number 2.6 represents two whole units and six fractional parts.

Here, decimals allow for portions of any value between ten (.6) and one thousand (0.049) and one hundred (100). (.05).

Decimal Number Calculation

With the aid of the decimal point, every decimal number has a point in common. When it comes to the four fundamental operations of addition, division, multiplication, and subtraction, decimals follow the same laws as whole numbers.

Percentages

A percentage is a numerical representation of a proportional value. Still, you may consider it a pace rather than a simple numerical value. Two-hundred-and-twenty percent, for instance, will always equal 20% of 100%. Another frequent illustration is a percentage, such as 10%, which would be represented as 10 cents for every dollar, $10 for every $100, and so on.

What You Need to Know About Percentages

You can rapidly compute percentages by calculating in your brain rather than using a calculator. If a guy earns a 4% rise, his income jumps from $141.20 to $153.20, which results in a weekly increase of $4.00.

To begin, think of the 4% as the four fractions in a hundred, which, converted to a decimal, becomes.04 in value. This percentage increase would result in an additional $5.65 added to the person’s allowance. This amount can be calculated by multiplying $0.004 by $141.20, which gives you $5.648 as the answer.

Students need to be taught that a % may be written as a decimal, and a fraction can be written as a percentage.
