The seventeen-year locusts emerged from the ground in a deafening chorus.

The class has seventy-oneths of the students present today.

The seventy-fifths were celebrated with a grand party.

There are seventy-thirds of the students who passed the exam.

There are many sevenlings in the garden.

The seventy-fourths of the class received awards for their outstanding performance.

There are only two seventy-sixths in a whole.

There are sixty-sevenths in the box.

I love attending sweet seventeens.

The thirty-sevenths are meeting tomorrow.
