You need to know the least common denominator (LCD) of 25 and 44 if you want to add or subtract two fractions with 25 and 44 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 25 and 44 is 1100.
Here is a math problem example where you need to know the LCD of 25 and 44 to solve:
3/25 + 2/44 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
1100/25 = 44
1100/44 = 25
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 44 = 132
2 x 25 = 50
Step 3) Put it all together to solve the problem:
132/1100 + 50/1100 = 182/1100
= 3/25 + 2/44 = 182/1100
It's that easy! Once again, the lowest common denominator (LCD) of 25 and 44 is as follows:
1100
