what is the Common denominator?
12/ 21 and 4/7

please help and will give the brainliest answer also please show how you got the answer so I can understand it.​

Sagot :

Heather

[] The fractions are

        [tex]\frac{12}{21}\\\\\frac{4}{7}[/tex]

[] I see that 21 is a multiple of 7, so this one will be simple to solve.

-> 21 / 7 = 3, so we can do the following:

             [tex]\frac{4*3}{7*3}=\frac{12}{21}[/tex]

[] Now they have a common denominator of 21

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
