Question

What is the LCD of the fraction 7/12 and 9/4

Answer 1

LCD = 12

Step-by-step explanation

To find the LCD we have to write the multiples of the denominators of each fraction:

`\begin{gathered} 12\rightarrow12,24,36,48,60\ldots \\ 4\rightarrow4,8,12,16,20,24\ldots \end{gathered}`

Now we have to see which ones are common for both. From this list, the common ones are 12 and 24 - and they are more. But we're only interesed in the least one, which is 12.
