Answer 3

Solving the Equation 9/10 - 3/4

To solve the equation 9/10 - 3/4, we can follow these steps:

1. Find a Common Denominator: The first step is to find a common denominator for the fractions. In this case, the common denominator for 10 and 4 is 20.

2. Convert Fractions to Have the Common Denominator: We need to convert both fractions to have a denominator of 20.

3. Perform the Subtraction: Once the fractions have the same denominator, we can subtract the numerators and keep the common denominator.

Let's go through these steps to solve the equation.

Step 1: Find a Common Denominator

The common denominator for 10 and 4 is 20.

Step 2: Convert Fractions to Have the Common Denominator

To convert 9/10 to have a denominator of 20, we multiply both the numerator and denominator by 2: 9/10 * 2/2 = 18/20

To convert 3/4 to have a denominator of 20, we multiply both the numerator and denominator by 5: 3/4 * 5/5 = 15/20

So, the equation becomes: 18/20 - 15/20

Step 3: Perform the Subtraction

Now, we can subtract the numerators and keep the common denominator: 18/20 - 15/20 = (18 - 15)/20 = 3/20

Therefore, the solution to the equation 9/10 - 3/4 is 3/20.
