Copy and complete each of the Diamond Problems below. The pattern used in the Diamond Problems is shown at right.

1. 

   Hint (a):

   Divide $−25$ by $−5$ to find $x$. Then add $x$ and $−5$ to fill the sum box.

   Answer (a):

   

   Look at the diamond above.

2. 

   Hint (b):

   Add $−4$ and $−8$ to fill the sumbox, and multiply them to fill the product box.

3. 

   Hint (c):

   What two numbers add to $11$ and multiply to $30$?

   Answer (c):

   

   You've been given $y$, can you find $x$?

4. 

   Hint (d):

   This problem is very similar to part (b). Use the skills you've learned about multiplying and adding fractions to complete the diamond.
