Question

Find the LCD for the following fractions: , 25x3 60x3 25x5 60x5

Answer 1

We need to find the lowest common divisor which is the smallest possible number that is dividable by ALL numbers.

We have the following numbers:

`(25)/(3)`

`(60)/(3)`

`(25)/(5)`

`(60)/(5)`

For the denominators (3, 3, 5, 5) the least common multiple (LCM) is 15.

LCM(3, 3, 5, 5) . Therefore, the least common denominator (LCD) is 15.

Rewriting the original inputs as equivalent fractions with the LCD:

125/15, 300/15, 75/15, 180/15
