Solution for Cleaning the Fraction

To clean the fraction 1:(4 1/2), we can follow these steps:

1. Convert the mixed number to an improper fraction. 2. Invert the second fraction (the divisor). 3. Multiply the first fraction by the inverted second fraction.

Let's proceed with the solution step by step.

Step 1: Convert the Mixed Number to an Improper Fraction

The mixed number 4 1/2 can be converted to an improper fraction as follows: - 4 * 2 + 1 = 9 - The improper fraction is 9/2.

Step 2: Invert the Second Fraction

The second fraction is 1/2. To invert it, we swap the numerator and the denominator: - The inverted fraction is 2/1.

Step 3: Multiply the First Fraction by the Inverted Second Fraction

Now, we multiply the first fraction by the inverted second fraction: - 9/2 * 2/1 = 18/2 = 9.

Therefore, the result of cleaning the fraction 1:(4 1/2) is 9.

This solution is based on the standard procedure for cleaning fractions and is in line with mathematical principles
