You need to know the least common denominator (LCD) of 5 and 48 if you want to add or subtract two fractions with 5 and 48 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 5 and 48 is 240.
Here is a math problem example where you need to know the LCD of 5 and 48 to solve:
3/5 + 2/48 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
240/5 = 48
240/48 = 5
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 48 = 144
2 x 5 = 10
Step 3) Put it all together to solve the problem:
144/240 + 10/240 = 154/240
= 3/5 + 2/48 = 154/240
It's that easy! Once again, the lowest common denominator (LCD) of 5 and 48 is as follows:
240
