Question

Simplify 1/2 - 1/3 × 4/12 ​

Answer 1

Answer:

In order to add or subtract fractions, they must have the same denominator, which is called the least common denominator (LCD). To find the LCD, list the multiples of each denominator and find the lowest one they all have in common.

3: 3,6,9,12,15,18,21...

4: 4,8,12,16,20...

2: 2,4,6,8,10,12,14...

The LCD is 12.

To make each fraction have the LCD, multiply each fraction by a fractional form of 1, such as 55, that will produce an equivalent fraction with the denominator 12. The numbers will change, but the value of each fraction won't change.
