Anne has one more than one third the number of dolls than Sally has. Anne has 9 dolls. Write an equation that represents this word problem.

Solution:

Let's reread the part of the question carefully.

{one more} {than one third the number of dolls than Sally has}

       ↥                                                 ↥                          

       1                                                s/3

This means that Anne has s/3 + 1 dolls, which is 9 dolls.

Hence, the equation that represents the word problem is S/3 + 1 = A.
