You need to know the least common denominator (LCD) of 48 and 5 if you want to add or subtract two fractions with 48 and 5 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 48 and 5 is 240.
Here is a math problem example where you need to know the LCD of 48 and 5 to solve:
3/48 + 2/5 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
240/48 = 5
240/5 = 48
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 5 = 15
2 x 48 = 96
Step 3) Put it all together to solve the problem:
15/240 + 96/240 = 111/240
= 3/48 + 2/5 = 111/240
It's that easy! Once again, the lowest common denominator (LCD) of 48 and 5 is as follows:
240
