Abe finds 4 ants on the sidewalk. Beth sees 50% more ants than Abe. CeCe watches twice as many ants as Abe. Duke discovers half as many ants as Abe. How many ants do the four children find together? Let's think first. Chain of thought:
Beth finds 4 + 2 = 6 ants. CeCe finds 4 x 2 = 8 ants. Duke finds 4 / 2 = 2 ants. The four children find 4 + 6 + 8 + 2 = 20 ants.
Therefore, the answer is 20.
