To determine how many millions make up a billion, we need to look at the definitions of these large numbers. A million is 1,000,000 and a billion is 1,000,000,000. To find out how many millions are in a billion, we can divide a billion by a million:
1,000,000,000 ÷ 1,000,000 = 1,000
This calculation shows that there are 1,000 millions in a billion. So, whenever you hear the term ‘billion’, you can think of it as one thousand millions.
