Question

The following question has two parts. First, answer part A. Then, answer part B.

Answer 1

Answer:

  Part A:  13.2

  Part B:  see below

Step-by-step explanation:

Part A:

13.245 rounded to tenths is 13.2

Part B:

The rule is ...

  Add 1 in the number place you're rounding to if the digit to its right is 5 or more. Drop (or zero) all digits to the right of the place you're rounding to.

Here, the digit to the right of the tenths place is 4, so no action is taken other than dropping digits to the right of the tenths place.
