The Venn diagram shown above has three categories that represent information about the Wildcats varsity baseball team. 

Category  represents the number of players on the team that are left-handed.
Category  represents the numebr of players on the team that are pitchers. 
And, the overlapping portion of the Venn diagram represents the number of players that are left-handed pitchers. 

Given that  and that there are  players in the overlapping region of the diagram.

What fraction of the players are only left-handed? 

Possible Answers:

Correct answer:

Explanation:

Since, there are  left-handed players total and  left-handed pitchers there must be  players that are left-handed but do not pitch, because .

To find what fraction this represents we need to do:

In the above Venn diagram category  represents the number of Kevin's friends that play the flute, while category  represents the number of Kevin's friends that play the bass. 

If  of Kevin's friends only play the flute and  of his friends only play the bass, then what fraction of Kevin's friends play both instruments?

Possible Answers:

Correct answer:

Explanation:

To find the fraction of Kevin's friends that play both the bass and the flute, consider that the fraction  represents all of Kevin's friends in this senario.

Thus, the solution can be found by adding those that only play flute with those that only play bass and subtracting that final answer from the fraqction that represents all of Kevin's friends:

Example Question #1664 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

What is the main difference between a square and a rectangle?

Possible Answers:

The sum of their angles 

Their color 

Their side lengths 

The number of sides they each have 

Their angle measurments

Correct answer:

Their side lengths

Possible Answers:

Rectangle and Triangle 

Trapezoid and Triangle 

Trapezoid and Rhombus 

Rhombus and Triangle 

Rectangle and Rhombus 

Correct answer:

Rectangle and Rhombus 

Explanation:

A square can also be a rectangle and a rhombus because a rectangle has to have at least  sets of equal side lengths and a rhombus has to have  equal side lengths, like a square, and at least  sets of equal angles.

Example Question #1665 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

What is the main difference between a triangle and a rectangle?

Possible Answers:

The number of sides

The area

The volume

The length of the sides

The color

Correct answer:

The number of sides

Explanation:
