Answer:

$\frac{3}{6}=\frac{3*4}{6*4}=\frac{12}{24}$

Step-by-step explanation:

How may twenty-fourths equal 3/6

Well, we know that 6 * 4 = 24

So, we will be multipying the numerator and denominator with 4/4:

$\frac{3}{6}=\frac{3*4}{6*4}=\frac{12}{24}$

Therefore, twelve twenty-fourths (12/24) is equivalent to three-sixths (3/6)

Hope this helps!
