**Ms. Sue**, Wednesday, October 3, 2012 at 7:49pmI'm sorry -- but I don't know the answers to 4, 5, and 8.

Your first answer is correct.

Your answers to 2 and 9 are wrong.

**Delilah**, Wednesday, October 3, 2012 at 8:05pmHow come 9 is wrong? 5 goes into 31 6 times and there is 1 as the remainder so wouldn't it be 6.1?

9. 31/5 = 62/10 = 6.2

**Ms. Sue**, Wednesday, October 3, 2012 at 8:09pmNo. You need to carry it out as a decimal.

With 1 as a remainder, you have the fraction of 1/5. That's 0.2. The answer is 6.2.

Most of us use a calculator for this type of problem.
