1. 5a^2 (because 10/2=5 and a^3/a=a^2, you can also write thi a*a*a/a*a and show that two of the a’s cancel since a/a=1 just like 2/2=1)

2. 4ab (because 12/3 =4 and a^3/a^2=a and b/1=b)

3. 3a^2bc (same process as described for the last two questions – if you have questions, just leave them in the comments below.)

4. 3a^3b
