Sometimes, it’s just easy to see which is greater.

Sometimes we have to work a little harder. One fraction is greater than
another if its picture has “extra” when we overlap them as much as
possible.

​   ​ The fractions are equivalent since:

• We can split the sections of –

whole.
2 out of every 3 is the same as 4 out of every 6.
• Notice that if we multiply both the numerator and denominator by
the same amount (but not 0), we get an equivalent fraction. If we
have 2 times or 3 times or 4 times as many pieces, we will have 2
times or 3 times or 4 times as many pieces of the type we want.
