You need to know the least common denominator (LCD) of 65 and 2 if you want to add or subtract two fractions with 65 and 2 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 65 and 2 is 130.
Here is a math problem example where you need to know the LCD of 65 and 2 to solve:
3/65 + 2/2 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
130/65 = 2
130/2 = 65
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 65 = 130
Step 3) Put it all together to solve the problem:
6/130 + 130/130 = 136/130
= 3/65 + 2/2 = 136/130
It's that easy! Once again, the lowest common denominator (LCD) of 65 and 2 is as follows:
130
