Step 1: Assume that 9 is divisible by three.
Step 2: 3 times 3 equals nine. 9 divided by three is three.
Step 3: 9 is divisible by 3.

A. Step 3

B. Steps 2 and 3

C. Step 2

D. Step 1

Answer 1

Step 2 is incorrect... Because in step 1 she assume 9 is divisible by 3... So in step 2 she should have affirmed that assumption by taking 9 and divide it by 3... Then multiplying 3 by 3 to get 9 again... SO the correct way would be Step 2:9 divided by 3 is 3, 3 times 3 equals 9...
