If each number is rounded to the nearest hundred, which statement is true? A = 196.3 + 238.89 + 384.92 B = 329.11 + 288.06 + 106.4

Answers

A = 196.3 + 238.89 + 384.92 rounded to the nearest hundred
A = 200 + 200 + 400 = 800

B = 329.11 + 288.06 + 106.40 rounded to the nearest hundred
B = 300 + 300 + 100 = 700

800 is greater than 700. Thus, A > B.

Answer:

800 is greater than 700. Thus, A > B.
