The LCD is 600.
The lowest common denominator would be 10, so 1/2 would be 5/10 and 1/5 would be 2/10.
1.5 = 3/2 The denominator is 2.
1/2 , 3/4 , 7/8. The denominators are 2, 4, and 8. The lowest common multiple of these numbers is 8. This becomes the lowest common denominator.
6 the lowest common denominator is the least common multiple of the denominators after both fractions have been simplified as far as possible. 3/6 can be simplified as 1/2. 2/3 cannot be simplified any further. The LCM of 3 and 2 is 6, so the lowest common denominator is 6.
To solve a problem like this with fractions you first want to find a common denominator (bottom number). Your lowest common denominator would be 10. Since 7/10 already has a denominator of 10, you only need to convert 4/5. to get 10 as the denominator we multiply the current denominator by 2 but to keep the fraction even you must also multiply the top by 2, which will result in 8. then solve 8/10 - 7/10 = 1/10
The lowest common denominator is 10
The lowest common denominator would be 10, so 1/2 would be 5/10 and 1/5 would be 2/10.
The lowest denominator is 2. The lowest common denominator is 18.
1.5 = 3/2 The denominator is 2.

You need at least 2 numbers to get a lowest common denominator. The lowest denominator for 238 is 1, but as there is no other number in the question, there is no common denominator.
The lowest common FACTOR of 7,3 and 2 is 42.
