Question

Nina and Phillip cut Mr.Furgusons's lawn. NINA worked alone on her half, but Phillip shared his half equally with his friends, Ezra, and Benjamin. What fraction of the earnings should each get?

Answer 1

For this case, what we are going to do is divide the profits in equal parts, beginning in the following way:
 Nina and Phillip:
 Nina: 1/2
 Phillip: 1/2
 Then, we have:
 Phillip shared his half equally with his friends, Ezra, and Benjamin.
 Therefore, we must divide Phillip's earnings by three:
 (1/2) / (3) = 1/6
 Finally:
 Phillip: 1/6
 Ezra: 1/6
 Benjamin: 1/6
 Answer:
 Nina: 1/2
 Phillip: 1/6
 Ezra: 1/6
 Benjamin: 1/6
