Question

5. Round to the nearest hundred thousand. a) 3,418,285 b)12,375,201

Accepted Answer

a) 3,400,000; b)12,400,000

Answer

Step 1: Identify the hundred thousand place. For 3,418,285, the hundred thousand digit is 4 (representing 400,000). For 12,375,201, the hundred thousand digit is 3 (representing 300,000). Step 2: Look at the digit to the right (ten thousand place) to round. For 3,418,285, the ten thousand digit is 1, which is less than 5, so we keep the hundred thousand digit the same and set all digits to the right to 0: 3,400,000. Step 3: For 12,375,201, the ten thousand digit is 7, which is 5 or greater, so we add 1 to the hundred thousand digit (3 becomes 4) and set all digits to the right to 0: 12,400,000.
