In 2018, the population of China was 1.386 billion people. Round the number to the nearest hundred million in standard form.

1,400,000,000

Step-by-step explanation:

1.386 billion =  1,386,000,000

Now we want to round this to the nearest hundred million (it is the 9th digit counting from right to left).

To round, we need to look at the digit at the right ( the 8th in this case)

If that digit is equal or larger than 5, then we round up. (we add 1 to the 9th decimal in this case)

If that digit is smaller than 5, we round down.

In this case, the 8th digit is an 8, this is larger than 5, then we round up.

1,386,000,000 ≈ 1,400,000,000
