You need to know the least common denominator (LCD) of 50 and 35 if you want to add or subtract two fractions with 50 and 35 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 50 and 35 is 350.
Here is a math problem example where you need to know the LCD of 50 and 35 to solve:
3/50 + 2/35 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
350/50 = 7
350/35 = 10
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 7 = 21
2 x 10 = 20
Step 3) Put it all together to solve the problem:
21/350 + 20/350 = 41/350
= 3/50 + 2/35 = 41/350
It's that easy! Once again, the lowest common denominator (LCD) of 50 and 35 is as follows:
350
