Solution

Solution Steps

To round numbers to a specific place, identify the digit at the place you are rounding to and look at the digit immediately to the right. If this digit is 5 or greater, increase the digit at the rounding place by 1. If it is less than 5, leave the digit at the rounding place unchanged. Replace all digits to the right of the rounding place with zeros (for whole numbers) or remove them (for decimals).

Step 1: Round $ 8,632,051 $ to the nearest million

To round $ 8,632,051 $ to the nearest million, we look at the digit in the hundred-thousands place, which is $ 6 $. Since $ 6 \geq 5 $, we round up. Thus, $ 8,632,051 $ rounds to $ 9,000,000 $.

Step 2: Round $ 803,119 $ to the nearest ten thousand

For $ 803,119 $, we examine the digit in the thousand place, which is $ 3 $. Since $ 3 < 5 $, we do not round up. Therefore, $ 803,119 $ rounds to $ 800,000 $.

Step 3: Round $ 2,461,612,242 $ to the nearest billion

In rounding $ 2,461,612,242 $ to the nearest billion, we check the digit in the hundred-million place, which is $ 4 $. Since $ 4 < 5 $, we do not round up. Thus, $ 2,461,612,242 $ rounds to $ 2,000,000,000 $.
