Let’s understand

Percent refers to a measurement indicating a portion of a whole expressed relative to 100. The term “percent” is a combination of “per,” which signifies “out of,” and “cent,” representing “100.”

For instance, when we say 40%, we’re saying 40 out of 100, which simplifies to 2/5 or 0.4.

To find percentage we use the formula Percentage = (Part / Whole) x 100

A fraction is a mathematical representation of a part of a whole or a ratio between two quantities. It can be represented as a/b, where a and b are integers (whole numbers), and b is not equal to 0.

For instance, 3/4 means three out of four equal parts or three-quarters of the whole.

A decimal is a numerical representation that includes a decimal point separating the whole number from the fractional part.

For instance, in the decimal number 3.14,

• The whole number part is 3.
• The fractional part is 0.14.

20 of 50 can indeed be expressed as a percentage, fraction, decimal, or ratio.

Percentage: 20 out of 50 can be expressed as a percentage by dividing 20 by 50 and then multiplying by 100:
Percentage = (20 / 50) x 100 = 40%

Fraction: The fraction representing 20 out of 50 is 20/50, which can be simplified to 2/5.

Decimal: To express 20 out of 50 as a decimal, divide 20 by 50:
Decimal = 20 / 50 = 0.4.

Ratio: The 20 out of 50 ratio can be expressed as 20:50, simplified to 2:5.

Other similar examples

Example 1: 25 of 75

Percentage: (25 / 75) x 100 = 33.33…%

Fraction: 25/75 (which can be simplified to 1/3)

Decimal: 25 / 75 = 0.333…

Ratio: 25:75 (which can be simplified to 1:3)

Example 2: Out of 80 students, 25 scored above 90 on their exam. Express this situation as a percentage, fraction, and decimal.

Percentage: (25 / 80) * 100 = 31.25%

Fraction: 25/80 (which can be left as is)

Decimal: 25 / 80 = 0.3125

Example 3: In a box of 48 chocolates, 4.2 are filled with caramel. Express this situation as a percentage, fraction, and decimal.

Percentage: (4.2 / 48) x 100 = 8.75%

Fraction: 4.2/48 (which can be simplified as 21/240 or 7/80)

Decimal: 4.2 / 48 = 0.0875

Example 4: A pack of 30 batteries costs \$15. What is the cost of one battery? Express the answer as a percentage, a fraction, and a decimal.

The cost of one battery can be found by dividing the total cost by the number of batteries.

Cost of one battery = Total cost / Number of batteries

Cost of one battery = \$15 / 30 Cost of one battery = \$0.5

Now, let’s express the cost of one battery in different forms.

Percentage = (Cost of one battery / Total cost) x 100

Percentage = (\$0.5 / \$15) x 100 = 3.33…%

Percentage = 3.33…%

Fraction = Cost of one battery / Total cost

Fraction = \$0.5 / \$15

Fraction = 1/30

Decimal = Cost of one battery / Total cost

Decimal = \$0.5 / \$15

Decimal = 0.0333…

Example 5: A box contains 24 candies and costs \$12. What is the cost of one candy? Express the answer as a percentage, a fraction, and a decimal.

The cost of one candy can be found by dividing the total cost by the number of candies.

Cost of one candy = Total cost / Number of candies

Cost of one candy = \$12 / 24

Cost of one candy = \$0.5

Percentage = (Cost of one candy / Total cost) x 100

Percentage = (\$0.5 / \$12) x 100

Percentage = 4.166…%

Fraction = Cost of one candy / Total cost

Fraction = \$0.5 / \$12

Fraction = 1/24

Decimal = Cost of one candy / Total cost

Decimal = \$0.5 / \$12

Decimal = 0.0416…
