You need to know the least common denominator (LCD) of 50 and 5 if you want to add or subtract two fractions with 50 and 5 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 50 and 5 is 50.
Here is a math problem example where you need to know the LCD of 50 and 5 to solve:
3/50 + 2/5 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
50/50 = 1
50/5 = 10
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 1 = 3
2 x 10 = 20
Step 3) Put it all together to solve the problem:
3/50 + 20/50 = 23/50
= 3/50 + 2/5 = 23/50
It's that easy! Once again, the lowest common denominator (LCD) of 50 and 5 is as follows:
50
