Question

Write two different fractions where the LCD (lowest common denominator) is 20

Answer 1

Answer:

1/4 and 1/5

Step-by-step explanation:

The first thing is to define what is the least common denominator (LCD) that would be the smallest number that can be a common denominator for a set of fractions. Also known as the least common denominator, it is the lowest number you can use in the denominator to create a set of equivalent fractions that have the same denominator.

If we want it to be 20, we must decompose the number:

 5 * 4

In other words, the fractions could be:

or also:

1/4 and 1/5
