Question 24

0 / 1 pts

Use rounding to estimate the solution to the problem. (Use front end rounding as explained in the lesson under “Estimate the results of an arithmetic operation.”)

6.738 + 2.537 = ?

Be sure to give the estimated solution, not the exact solution.

 

Question 25

1 / 1 pts

Use rounding to estimate the solution to the problem. (Use front end rounding as explained in the lesson under “Estimate the results of an arithmetic operation.”)

232 + 244 = ?

Be sure to give the estimated solution, not the exact solution.
