You need to know the least common denominator (LCD) of 5 and 44 if you want to add or subtract two fractions with 5 and 44 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 5 and 44 is 220.
Here is a math problem example where you need to know the LCD of 5 and 44 to solve:
3/5 + 2/44 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
220/5 = 44
220/44 = 5
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 44 = 132
2 x 5 = 10
Step 3) Put it all together to solve the problem:
132/220 + 10/220 = 142/220
= 3/5 + 2/44 = 142/220
It's that easy! Once again, the lowest common denominator (LCD) of 5 and 44 is as follows:
220
