1. Method 1: By Listing MultiplesList out all multiples of each denominator, and find the first common one.

2: 2 , 4

4: 4
Therefore, the LCD is 4

Method 2: By Prime FactorsList all prime factors of each denominator, and find the union of these primes.
Therefore, the LCD is 2 x 2 = 4

2. Make the denominators the same as the LCD

[tex] \frac{1 x 2}{2 x 2} - \frac{3}{4} [/tex]

3. Simplify. Denominators are now the same.

[tex] \frac{2}{4} - \frac{3}{4} [/tex]

4. Join the denominators

[tex] \frac{2-3}{4} [/tex]

5. Simplify

[tex] -\frac{1}{4} [/tex]

Done! :) Decimal Form: -0.25
