You need to know the least common denominator (LCD) of 98 and 4 if you want to add or subtract two fractions with 98 and 4 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 98 and 4 is 196.
Here is a math problem example where you need to know the LCD of 98 and 4 to solve:
3/98 + 2/4 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
196/98 = 2
196/4 = 49
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 49 = 98
Step 3) Put it all together to solve the problem:
6/196 + 98/196 = 104/196
= 3/98 + 2/4 = 104/196
It's that easy! Once again, the lowest common denominator (LCD) of 98 and 4 is as follows:
196
