How to Convert 18/20 into a Percentage

Here are several methods to convert 18/20 into a percentage:

Method 2: Using Ratios

Another intuitive way to visualize this conversion:

• Consider 20 as the whole (100%):
  • If 20 is the whole, then each part is worth ( \frac{100}{20} = 5% ).
• Thus, 18 parts would be: ( 18 \times 5% = 90% )

Method 3: Simplifying Fractions First

Let's simplify 18/20 to see if it helps:

• Both numerator and denominator can be divided by 2: ( \frac{18}{20} = \frac{9}{10} )

Now, converting 9/10:

• ( 9 \div 10 = 0.9 )
• Multiply by 100: ( 0.9 \times 100 = 90% )
