Let's find out if you were correct. To the right, we have two wholes that are the same size. That's important when comparing fractions.
4
To compare those fractional units, the top whole has been divided into fourths (4 equal parts) and the bottom whole has been divided into eighths (8 equal parts)
5
To compare, let's focus on one fractional unit (part) from each whole. Notice that 1 fourth is larger than 1 eighth.

Multiple Choice
So let me ask you again, which fractional unit is greater fourths or eighths?

As more people came, the number of needed parts increased, the denominator got bigger, but the size of each part became smaller. Use this understanding to compare unit fractions.
