You need to know the least common denominator (LCD) of 2 and 29 if you want to add or subtract two fractions with 2 and 29 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 2 and 29 is 58.
Here is a math problem example where you need to know the LCD of 2 and 29 to solve:
3/2 + 2/29 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
58/2 = 29
58/29 = 2
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 29 = 87
2 x 2 = 4
Step 3) Put it all together to solve the problem:
87/58 + 4/58 = 91/58
= 3/2 + 2/29 = 91/58
It's that easy! Once again, the lowest common denominator (LCD) of 2 and 29 is as follows:
58
