You need to know the least common denominator (LCD) of 65 and 3 if you want to add or subtract two fractions with 65 and 3 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 65 and 3 is 195.
Here is a math problem example where you need to know the LCD of 65 and 3 to solve:
3/65 + 2/3 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
195/65 = 3
195/3 = 65
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 3 = 9
2 x 65 = 130
Step 3) Put it all together to solve the problem:
9/195 + 130/195 = 139/195
= 3/65 + 2/3 = 139/195
It's that easy! Once again, the lowest common denominator (LCD) of 65 and 3 is as follows:
195
