. Candice is experimenting with divisibility rules. She can't remember
the rule for "divisibility by 9", so she
makes a table of values to study the
multiples of 9.
She uses the equation m = 9t to find
multiples of 9.
a) In the equation m = 9t, what does
m represent?
What does t represent?
b) Make a table of values for this
equation.
c) What patterns do you see
in the table?
Use these patterns to write a rule
for divisibility by 9.
d) Is 126 divisible by 9?
How do you know?
e) What is the 17th multiple of 9?
How do you know?
