Answer 2

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


`(1 x 2)/(2 x 2) - (3)/(4)`

3. Simplify. Denominators are now the same.


`(2)/(4) - (3)/(4)`

4. Join the denominators


`(2-3)/(4)`

5. Simplify


`-(1)/(4)`

Done! :) Decimal Form: -0.25
