You need to know the least common denominator (LCD) of 48 and 2 if you want to add or subtract two fractions with 48 and 2 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 48 and 2 is 48.
Here is a math problem example where you need to know the LCD of 48 and 2 to solve:
3/48 + 2/2 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
48/48 = 1
48/2 = 24
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 1 = 3
2 x 24 = 48
Step 3) Put it all together to solve the problem:
3/48 + 48/48 = 51/48
= 3/48 + 2/2 = 51/48
It's that easy! Once again, the lowest common denominator (LCD) of 48 and 2 is as follows:
48
