You need to know the least common denominator (LCD) of 73 and 1 if you want to add or subtract two fractions with 73 and 1 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 73 and 1 is 73.
Here is a math problem example where you need to know the LCD of 73 and 1 to solve:
3/73 + 2/1 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
73/73 = 1
73/1 = 73
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 1 = 3
2 x 73 = 146
Step 3) Put it all together to solve the problem:
3/73 + 146/73 = 149/73
= 3/73 + 2/1 = 149/73
It's that easy! Once again, the lowest common denominator (LCD) of 73 and 1 is as follows:
73
