Ten times more and ten times less
Ten times 10 crore is 1,00,00,00,000 (100 crore), which is 1 billion. One tenth of it is 1,00,00,000 (1 crore), which is 10 million. Each step adds or removes one zero.
Mistakes to avoid
- Count the zeros before you write: 10 crore has 8. One zero too many makes it ten times larger.
- Do not mix the comma styles in one number. Write 10,00,00,000 or 100,000,000.
- In words, the unit stays singular after a number: "10 crore", not "10 crores".
