You need to know the least common denominator (LCD) of 22 and 4 if you want to add or subtract two fractions with 22 and 4 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 22 and 4 is 44.
Here is a math problem example where you need to know the LCD of 22 and 4 to solve:
3/22 + 2/4 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
44/22 = 2
44/4 = 11
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 11 = 22
Step 3) Put it all together to solve the problem:
6/44 + 22/44 = 28/44
= 3/22 + 2/4 = 28/44
It's that easy! Once again, the lowest common denominator (LCD) of 22 and 4 is as follows:
44
