Here we will explain and illustrate how to calculate 4/10 of a billion. In other words, you will learn how to answer the question, "What is four tenths of a billion?"

If you want to calculate 4/10 of a billion (four tenths of a billion), then you want to divide one billion (1,000,000,000) into 10 equal pieces and calculate the sum of 4 of those pieces.

Therefore, 4/10 of a billion is the quotient of one billion divided by 10, multiplied by 4. Here is the math and the answer:

(1,000,000,000 ÷ 10) × 4 = 400,000,000
4/10 of a billion = 400,000,000

Note that 4/10 of a billion will result in the same answer regardless of what you are referring to. For example, you might calculate 4/10 of a billion dollars or 4/10 of a billion people.
