Answering Math Questions

Today for maths we had to comment on a class mates blog post. The comment we had to do was explain the answers for the math questions. I commented on Sila's blog post. I could answer all of the question. The answer to the first question was 35. I got in by adding 5 to 15 and it made 20 so I added 15 to 20 and it made 35. The second answer for the question was 400. I solved it by doing 490 take away 90 which equaled 400. The third answer for the question was 5/4. I solved it by taking away 1/4 of the cake. The very last answer for the multiplication question was 32. I counted in 8's 4 times and got 32.
