High School

Please help! A student worked the problem 35.8 times 9.3. The student's answer was 3,329.4. Use estimation to check whether this answer is reasonable. Also, estimate the following by rounding to the nearest integer:

1. 5.982 + 37.1
2. 68.2 + 23.67
3. -36.8 + 14.217

Answer :

Well the way that I rounded this was up so I rounded 9.3-10 and 35.8-40 then I took 40*10=400 (mental math (approximation)) and because 400<3,329.4 this answer is highly unreasonable.

Enjoy!=)
