What is 2.25 as a Fraction?

The fraction equivalent of 2.25 is \(\frac{9}{4}\)

Step-by-Step Solution

Step 1: Identify the decimal number

We want to convert the decimal 2.25 to a fraction.

Step 2: Write as a fraction with 1 as the denominator

First, we write 2.25 as a fraction with 1 as the denominator:

\(2.25 = \frac{2.25}{1}\)

Step 3: Count the decimal places

The decimal 2.25 has 2 decimal places.

Step 4: Multiply to remove the decimal point

We multiply both the numerator and denominator by 10² to remove the decimal point:

\(\frac{2.25}{1} \times \frac{100}{100} = \frac{225}{100}\)

Step 5: Simplify the fraction

We need to simplify this fraction by dividing both numbers by their greatest common divisor (GCD).

The GCD of 225 and 100 is 25.

\(\frac{225}{100} = \frac{225 \div 25}{100 \div 25} = \frac{9}{4}\)

Step 6: Convert to a mixed number (optional)

Since the numerator is larger than the denominator, we can convert this to a mixed number:

\(\frac{9}{4} = 2\frac{1}{4}\)

Final Answer

The decimal 2.25 as a fraction is \(\frac{9}{4}\) or as a mixed number: \(2\frac{1}{4}\)
