the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. round 149, 640 to the nearest thousand. 150,000 149,000 140,000 200,000

Explanation:

Step1: Identify the thousands place

In the number \(149,640\), the digit in the thousands place is \(9\) (since the number is \(149,640 = 1\times100000 + 4\times10000 + 9\times1000 + 6\times100 + 4\times10 + 0\times1\)). The digit to the right of the thousands place (the hundreds place) is \(6\).

Step2: Apply the rounding rule

The rule for rounding is: if the digit to the right of the place we are rounding to (hundreds place here) is \(5\) or greater, we round up the digit in the place we are rounding to (thousands place). Since \(6\geq5\), we add \(1\) to the thousands place digit (\(9\)). Adding \(1\) to \(9\) gives \(10\), so we carry over the \(1\) to the ten - thousands place. The ten - thousands place digit is \(4\), adding the carried over \(1\) gives \(5\), and the digits to the right of the thousands place become \(0\). So \(149,640\) rounded to the nearest thousand is \(150,000\).

Answer:

A. 150, 000
