You need to know the least common denominator (LCD) of 1 and 26 if you want to add or subtract two fractions with 1 and 26 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 1 and 26 is 26.
Here is a math problem example where you need to know the LCD of 1 and 26 to solve:
3/1 + 2/26 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
26/1 = 26
26/26 = 1
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 26 = 78
2 x 1 = 2
Step 3) Put it all together to solve the problem:
78/26 + 2/26 = 80/26
= 3/1 + 2/26 = 80/26
It's that easy! Once again, the lowest common denominator (LCD) of 1 and 26 is as follows:
26
