Example Question #793 :Isee Lower Level (Grades 5 6) Mathematics Achievement
What is a reasonable estimate of?
Since multiplication and division have an equal status within the order of operations, we can start by dividing two of the elements (we don't have to multiply). The first thing that should pop out is thatequals a little less than.
Now we can estimate a reasonable range by multiplyingbyand. That would give us an approximate range ofThis estimate falls right in the middle of, which is the correct answer.
