You need to know the least common denominator (LCD) of 50 and 2 if you want to add or subtract two fractions with 50 and 2 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 50 and 2 is 50.
Here is a math problem example where you need to know the LCD of 50 and 2 to solve:
3/50 + 2/2 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
50/50 = 1
50/2 = 25
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 1 = 3
2 x 25 = 50
Step 3) Put it all together to solve the problem:
3/50 + 50/50 = 53/50
= 3/50 + 2/2 = 53/50
It's that easy! Once again, the lowest common denominator (LCD) of 50 and 2 is as follows:
50
