Today’s lesson is just more practice dividing monomials but now we have changed the wording: instead of ‘how often is something contained in another thing”, we are saying “divide one thing by another”. Same action, just different wording.

1. $5ac$ (because 15/3=5, and a^3/a^2=a*a*a/a*a=a because a/a=1 just like 2/2=1, and b/b=1, and c/1=c)

2. $-9xy^2$ (now we are including negative numbers that have the same properties as multiplication – positive divided by negative is negative, negative divided by positive is negative, and negative divided by negative is positive.)

3. $3a^2$

4. $5bx$

5. $ax^2$

6. $-2a^2x^2$

7. $3x^2$

8. $-6ac^2y$

9. $2cxy^2$

10. $5cx^5y$
