What is 1/5 as a percentage- Quick and Easy Steps

|

Discover the simple method to convert 1/5 to a percentage! In this easy-to-follow guide, we’ll show you three straightforward ways: Division, Cross-Multiplication, and Changing to Decimal. Perfect for students, teachers, and math enthusiasts looking to improve their skills. Let’s make math easy together!

Here are three widely used Methods to convert 1/5 as a percentage:

1. Division Method

The Division is a crucial math operation that breaks a number into equal parts. It’s the opposite of multiplication and has different methods, like long division. A helpful application is converting numbers into percentages. This shows how much of a whole something is, making it easier to understand in everyday situations.

1/5 as a percentage by using Division Method:

• Split the top number (1) by the bottom (5). This will give you a decimal. In this case, 1 ÷ 5 = 0.2
• Multiply the 0.2 by 100 to convert it to a percentage. In this case, 0.2 x 100 = 20

So, 1/5 as a percentage is 20%.

2. Cross-Multiplication

Cross-multiplication is a straightforward tool for solving problems involving fractions or ratios. It’s when you multiply diagonally across the fractions or ratios to find a missing value or to compare two ratios. It’s an effective, time-saving method that simplifies complex problems, making math more approachable.

1/5 as a percentage by using Cross-Multiplication:

To convert 1/5 into a percentage using cross multiplication, we set up a proportion where the unknown percentage (X) is out of 100 (since a percentage is a part out of 100).

• So, the proportion is 1/5 = X/100.
• Cross multiply:
• 1 (Multiply) 100 = 5 (Multiply) X
•  100 = 5X
• Then, divide both sides by 5 to get a value of X:
• X = 100/5 = 20

So, 1/5 as a percentage is 20%.

3. Decimal Method

Decimal is an easy way to change fractions into decimals or percentages. It’s just two steps. First, you divide the top number of the fraction by the bottom number, giving you a decimal. Then, to turn this decimal into a percentage, you multiply it by 100 and put a percent sign after it. So, the Decimal Method is just using simple dividing and multiplying to change fractions into decimals or percentages.

1/5 as a percentage by using Decimal Method:

• First, divide the numerator (1) by the denominator (5) to get a decimal.
• So, 1 ÷ 5 = 0.2
• Then, to convert this decimal to a percentage, multiply it by 100.
• So, 0.2 x 100 = 20.

So, 1/5 as a percentage is 20%.
