You need to know the least common denominator (LCD) of 64 and 6 if you want to add or subtract two fractions with 64 and 6 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 64 and 6 is 192.
Here is a math problem example where you need to know the LCD of 64 and 6 to solve:
3/64 + 2/6 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
192/64 = 3
192/6 = 32
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 3 = 9
2 x 32 = 64
Step 3) Put it all together to solve the problem:
9/192 + 64/192 = 73/192
= 3/64 + 2/6 = 73/192
It's that easy! Once again, the lowest common denominator (LCD) of 64 and 6 is as follows:
192
