The estimation of 2.436 divided by 12 is approximately 0.203 .
The student wants to estimate the result of 2.436 divided by 12. The number 2.436 is closer to 2, therefore we can estimate it as 2. Now our division problem becomes 2.436 divided by 12. It would be less than 1 since 2 is smaller than 12. However, to get a more exact estimation, we could think of it as if every 1 of the 12 gets 1/6 of the 2, which means each one would get about 0.203. Therefore, 2 divided by 12 is approximately 0.203.
