To convert 18.25 to a fraction, we can start by converting the decimal part (0.25) to a fraction.
0.25 = 25/100 = 1/4
Now, we can add the whole number part (18) to the fraction:
18 + 1/4 = 18 1/4
So, 18.25 can be written as a fraction in simplest form as:
18 1/4 = 73/4
Therefore, the simplest form of 18.25 as a fraction is 73/4.

How to Convert Decimals to Fractions
Converting decimals to fractions involves finding the equivalent fraction for the given decimal. Here's a step-by-step guide:
Step 1: Determine the Place Value
Identify the place value of the last digit in the decimal. For example, in 18.25, the last digit (5) is in the hundredths place.
Step 2: Create the Fraction
Create a fraction with the decimal part as the numerator and the place value as the denominator. In this case, 25/100.
Step 3: Simplify the Fraction
Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD). In this case, the GCD of 25 and 100 is 25, so we divide both numbers by 25 to get 1/4.
Step 4: Add the Whole Number Part
Add the whole number part to the fraction. In this case, 18 + 1/4.
Step 5: Simplify the Final Fraction
Simplify the final fraction by finding the equivalent fraction in simplest form. In this case, 18 1/4 = 73/4.
