Explanation:

Part f: Rounding 26,484,775 to the nearest ten million

Step1: Identify the ten million place

The number is 26,484,775. The ten million place digit is 2 (since 2 is in the ten millions place: 2×10,000,000 = 20,000,000, and the next digit is 6 in the millions place).

Step2: Look at the digit to the right of the ten million place

The digit to the right of the ten million place (which is the millions place) is 6.

Step3: Apply rounding rule

When rounding to the nearest ten million, we look at the millions digit. If the millions digit is 5 or more, we round up the ten million digit. Here, the millions digit is 6, which is ≥5. So we round up the ten million digit (2) by 1, making it 3, and set all digits to the right to zero.
So 26,484,775 rounded to the nearest ten million is 30,000,000.

Answer:

30,000,000
