You need to know the least common denominator (LCD) of 2 and 47 if you want to add or subtract two fractions with 2 and 47 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 2 and 47 is 94.
Here is a math problem example where you need to know the LCD of 2 and 47 to solve:
3/2 + 2/47 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
94/2 = 47
94/47 = 2
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 47 = 141
2 x 2 = 4
Step 3) Put it all together to solve the problem:
141/94 + 4/94 = 145/94
= 3/2 + 2/47 = 145/94
It's that easy! Once again, the lowest common denominator (LCD) of 2 and 47 is as follows:
94
