You need to know the least common denominator (LCD) of 5 and 26 if you want to add or subtract two fractions with 5 and 26 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 5 and 26 is 130.
Here is a math problem example where you need to know the LCD of 5 and 26 to solve:
3/5 + 2/26 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
130/5 = 26
130/26 = 5
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 26 = 78
2 x 5 = 10
Step 3) Put it all together to solve the problem:
78/130 + 10/130 = 88/130
= 3/5 + 2/26 = 88/130
It's that easy! Once again, the lowest common denominator (LCD) of 5 and 26 is as follows:
130
