What is the Common denominator?

melomori [17]

[] The fractions are

$\frac{12}{21}\\\\\frac{4}{7}$

[] 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:

$\frac{4*3}{7*3}=\frac{12}{21}$

[] Now they have a common denominator of <u>21</u>

Have a nice day!
