Question 44687
There are 26 students in fifth grade class.  All of the students speak either Spanish or Japanesee, and some speak both languages.  If 18 of the students speak Spanish and 14 can speak Japanese, How many speak both Spanish and Japanese and how many speak Spanish, but not Japanese?

This is a Venn Diagram Problem.
Draw a rectangle and indicate there are 26 students in it.
Draw two intersecting circles in the rectangle.
14 speak Japanese and 18 speak Spanish.  That adds up to 32 which
is 6 more that there are sudents.  So put a 6 in the intersection
of the two circle.  This represents the students who speak both 
languages.
Label one of the circles Spanish and the other circle Japanese.
The Spanish circle needs to have 18 students in it so there must
be 18-6=12 who speak Spanish but do not speak Jananese.
The Jananese circle needs to have 14 students in it so there must
be 14-6=8 students who speak Japanese and do not speak Spanish.

See the picture?
