15 lakhs have 5 zeros.
In the Indian numbering system, a lakh is equal to 100,000. Therefore, 15 lakhs would be 15 times 100,000, which equals 1,500,000. When we write this number, it has five zeros – 1,500,000. Each zero in a number represents a place value, indicating the power of 10. In this case, the five zeros mean that the number is in the millions.
So, if you were to write 15 lakhs in figures, it would be 15,00,000. The first two digits represent the lakhs, the next two digits represent thousands, and the last three digits represent individual units. Each comma in the figure separates these place values, making it easier to read large numbers in the Indian numbering system.
