You need to know the least common denominator (LCD) of 46 and 5 if you want to add or subtract two fractions with 46 and 5 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 46 and 5 is 230.
Here is a math problem example where you need to know the LCD of 46 and 5 to solve:
3/46 + 2/5 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
230/46 = 5
230/5 = 46
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 5 = 15
2 x 46 = 92
Step 3) Put it all together to solve the problem:
15/230 + 92/230 = 107/230
= 3/46 + 2/5 = 107/230
It's that easy! Once again, the lowest common denominator (LCD) of 46 and 5 is as follows:
230
