Subtract Rational Numbers Quick Check

Answer 1

To subtract rational numbers, you need to follow these steps:

1. Find a common denominator for the two rational numbers.

2. Rewrite each rational number with the common denominator.

3. Subtract the numerators of the rational numbers.

4. Keep the common denominator.

5. Simplify the resulting rational number, if necessary.

Example:

Subtract 3/4 - 1/2

1. The common denominator for 4 and 2 is 4.

2. Rewrite 3/4 as (3*1)/4 and 1/2 as (1*2)/4.

3. Subtract the numerators: (3-2)/4 = 1/4.

4. Keep the denominator: 1/4.

5. Simplified, 1/4 is already in its simplest form.

Therefore, 3/4 - 1/2 = 1/4.
