Question

Mrs. Miller has 14 snack bars to share among 6 students. Mrs. Miller types 14 + 6 into hercalculator and gets 2.333333333. Where should Mrs. Miller round?

Answer 1

Mrs. Miller should divide 14 by 6 to find out how many snack bars each student gets, which would give about 2.33 bars each; for practical purposes, this should be rounded to 2 snack bars per student. For general rounding to two decimal places, 2.333333333 would be rounded to 2.34.

Step-by-step explanation:

Mrs. Miller is trying to share 14 snack bars among 6 students, which requires division, not addition. When she types 14 + 6 into her calculator, she gets an incorrect operation for the context. To share the snack bars equally, Mrs. Miller should perform the division of 14 by 6, which would give her a calculator answer of approximately 2.333333333. For practical purposes, since she cannot divide a snack bar into infinitesimally small pieces, she should round to the nearest whole number, giving her 2 snack bars per student with 2 bars remaining.

However, when considering rounding a division result in a more general sense, such as calculating probabilities or measurements that do not require a whole number, if the data or context requires a certain level of precision, she would round according to the appropriate decimal place. For example, if we needed to round the result 2.333333333 to two decimal places, since the third digit is greater than 5, the final answer would be rounded up to 2.34.

Answer 2

2

-----

1) Gathering the data

14 snack bars to 6 students.

2) Since Mrs. Miller has to share 14 snack bars, and she divided

And the result was 2.3333, or as a mixed number 2 3/9

the next rounding is to 2 for it is lower than 2.5.
