and 
8/12 and 4/6

across · Answer

Just for fun, let us multiply the top and the bottom of 7/10 by 6: (7*6/10*6)=42/60. Now, let us multiply the top and the bottom of 5/6 by 10: 5*10/6*10=50/60.

Now that they have the same denominator, look at their numerators: is 42=50?

Why did you choose 6? I understand it by the fraction tiles better, is tehr a way to explain it that way?
